RumBoot Loader Tools

Summary

This repository is home to a set of tools to create, update and run rumboot v1, v2 and other images This repository contains several tools

rumboot-packimage - Adds/prints/updates checksums in image files
rumboot-xrun - Directly executes images via serial line or network
rumboot-xflash - Write on-board memories via serial line or network
rumboot-flashrom - Wrapper around flashrom tool for advanced SPI flash programming
rumboot-daemon - Provides network shared access to different boards

Sounds like too much? How you are you expected to use them in your app?

Use rumboot-packimage to add valid checksums to your binaries, so that bootrom would accept them
Run them via UART using rumboot-xrun (or your favourite jtag tool), flash them via rumboot-xflash
If rumboot-xflash doesn't work with your SPI Flash chip, check out rumboot-flashrom instead
Have only one board for a few developers? Want easy remote access during COVID-19 or some other epidemic? Check out rumboot-daemon.
Want to combine a set of tests into one image? Check out the rumboot-combine tool.

Chip IDs

rumboot-tools use IDs to identify chips. Every supported chip has it's own id.

Platform Name	Part Number	EDCL	Endianess	#Cores	ChipID	ChipRev	Image Format
mm7705	1888ТХ018	Yes	big	2	1	1	RumBoot V1
mb7707	К1879ХБ1YA	Yes	little	-	2	1	Legacy K1879XB1YA
basis	1888ВС048	No	little	1	3	1	RumBoot V2
oi10	1888ВМ018(A)/1888ВМ01H4	Yes	big	1	4	1	RumBoot V2
bbp3	1888ВС058	Yes	little	1	5	1	RumBoot V2
nm6408	1888ВС058	Yes	little	1	6	1	Legacy NM6408

          |                          |      |           |        |        |         |

zed | Zed Board / Tang Hex | No | little | 2 | 255 | 1 | Other rpi4 | BCM2711 (Raspberry Pi 4) | No | little | 4 | 255 | 2 | Other

Since different chips have different ROM loaders, default baudrates, flash memories and etc., some tools require you either set ChipId explicitly (via -c option) or try their best to guess it from image file header. Only newer (rumboot V2 and later) image formats have a dedicated field called chip_id.

You can either specify chip id via it's number or via platform name, whichever suits you. (-c 2 and -c mb7707 do the same).

For rumboot v2 and later, if the chip id doesn't match the one in silicon, the image is considered invalid

Thirdparty chips that are used for testing and prototyping always have chip id set as 255.

The chip revision may be used to distinguish different versions of the same chip, if any. It is only supported by Rumboot V2 headers and later. If Chip revision of the file you are uploading and the one stored in silicon don't match - you'll get a warning.

EDCL Notes

Basic stuff

Uart is the simplest possible interface for all debugging stuff, but it's also quite slow if you are going to send huge files (e.g. linux kernel, initrd, etc.) Starting with version 0.9.4 rumboot-tools support a side-channel to do data transfers. Right now the only possible sidechannel is EDCL.

EDCL stands for 'Ethernet communications debug link'. It provides a way to access physical memory via a special protocol over UDP. It exists in all RC Module's chips (except 'basis' platform). The protocol has NO security at all, so please disable edcl in a production enviroment. If you didn't get it, I'll write it in bold:

*NEVER EVER ENABLE EDCL IN A PRODUCTION ENVIRONMENT OR YOU'LL MAKE EASY PREY FOR HAX0RS!!! *

Setting up network for EDCL

EDCL IP and MAC adresses are hardcoded in silicon. Therefore putting several same chips in one LAN is not likely to work. The recommended setup is a dedicated network interface directly connected to the target board.

IP: 192.168.0.1 NetMask 255.255.0.0

After the interface setup is done, just add -e option for xrun/xflash and enjoy the speedup

ARP Bugs and workarounds

Some old chips have an invalid IP set as 192.168.0.0. The OS will discard ARP replies as invalid. However since EDCL only checks mac, we can set a static ARP record. The xrun does that automatically when needed using sudo/runas on linux/windows respectively. If a static record exists, no static record is added. When this hack is needed - you'll see UAC request in windows. In linux sudo will ask you for a password.

IP clash bug and workarounds

Okay, so despite the warning above, you want to use several different chips in the same LAN and noticed that different chips (e.g. mm7705 and oi10) have the same IP, though MACs are unique. There's a special flag called --force-static-arp that make xrun/xflash always drop existing arp records (if any) and add proper ones. Just note that this usage case is not 'officially' supported and can cause confusion of you don't fully understand what's happening.

Installation

From pypi (Recommended for Linux)

This is the simplest way. Just type:

    pip3 install rumboot-tools

    pip3 install rumboot-tools

And you're all set.

WARNING: Windows installations need Visual Studio Build Tools installed. It’s a huge download, but it’s needed. Grab it at Microsoft download site.

HINT: We provide binary offline windows installers for some released versions. The don't need those and are easier to install.

From a binary release zip (Recommended for Windows)

Grab a zip download from Github Releases Page or directly from the artifacts tab of Appveyor CI Page

The zip must match the python version currently installed. Unzip the archive and run either install_system.cmd or install_venv.cmd

install_system.cmd installs rumboot-tools and all dependencies into system directories and they are accessible immediately after installation.
install_venv.cmd installs rumboot-tools and all dependencies into 'venv' directory (will be created). Add venv\Scripts to your %PATH% to run tools from the command line.

From source (Linux, Windows)

This is pretty much as simple as it is. Just run the following:

    pip3 install .

    pip3 install .

P.S. Make sure you have a proper internet connection, or pip will fail to fetch dependencies.

optional arguments:
  -h, --help            show this help message and exit
  -f FILE, --file FILE  image file
  -i, --info            Show information about the image
  -c, --checksum        This option will modify the file! Calculates valid
                        checksums to the header. The length is set to cover
                        the full length of file ONLY if it's zero.
  -C, --checksum_fix_length
                        This option will modify the file! The same as
                        --checksum/-c, but always overrides length to covert
                        the full length of file
  -r, --raw             Display raw header field names
  -R relocation, --relocate relocation
                        Tell bootrom to relocate the image at the specified
                        address before executing it. Only RumBootV3 and above
  -Z, --compress        Compress image data with heatshrink algorithm (V3 or
                        above only)

                        the file (after checksummed area). This is required to
                        avoid propagating 'X' during the next image check
                        during simulation. Normally, you do not need this
                        option
  -a value, --align value
                        Pad resulting image size to specified alignment.
                        Remember to add -C to have correct checksums!
  -F value value, --flag value value
                        Set image flag to a desired value. Only RumBootV3 or
                        above
  --set-data offset value
                        Sets data at byte 'offset' to value 'offset'
  -g key, --get key     Get a single field from header. Nothing else will be
                        printed. NOTE: The value will be formatted as hex
  -s key value, --set key value
                        This option will modify the file! Set a header key to
                        specified value. Use -r flag on an existing image to
                        find out what keys exist. Use -c to update the
                        checksums
  -e, --reverse-endianness
                        Use this option to reverse endianness of all headers.
                        This will not touch data. For testing only
  -w WRAP, --wrap WRAP  Use this option to wrap arbitrary data to V1/V2/V3
                        images.

Typical uses

Check if an image file is valid

~# rumboot-packimage -f myimage.bin

Configuration file

The rumboot-xrun tries to find a configuration file on your system in the following locations:

~/.rumboot.yaml
/etc/rumboot.yaml

Example configuration file is provided below:

xrun:
    defaults:
        port: /dev/ttyUSB0
    chips:
        oi10:   
            port: /dev/ttyUSB1
            baudrate: 19200
        basis:  
            port: /dev/ttyUSB2
        mm7705: 
            port: socket://10.7.11.59:10002

The configuration file contains default ports and speeds for all known chip ids. If you supply a file to rumboot-xrun without any other options, rumboot-xrun will find out the chip id from the header file and set default port and baudrate accordingly.

If no configuration file can be found in any location, the default serial port will be /dev/ttyUSB0. Default baudrate will be taken from the internal chip database and should match most typical settings

Typical usage

Execute a file on bare metal enviroment

~# rumboot-xrun -f myimage.bin -p /dev/ttyUSB0
Detected chip:    oi10 (1888ВМ018(A)/1888ВМ01H4)
Reset method:     None
Baudrate:         115200 bps
Port:             /dev/ttyUSB0
Please, power-cycle board

Hello, World!
boot: host: Back in rom, code 0

This command waits for bootrom prompt, uploads a file via xmodem and prints everything received to stdout acting pretty much the same, as your favorite terminal program. The exit code from the program will be the exit code of rumboot-run (0 in the example above), therefore you can rumboot-xrun in your scripts during unit-testing.

NOTE: Make sure the jumpers on the board are set to 'host mode'. After running the command press the reset button or supply power to the board.

This command resets the board, uploads u-boot spl, u-boot and enters interactive mode for you to play with. The uploads are performed using edcl side-channel.

Execute a file, custom port/speed, automatically reset board via pl2303

~# rumboot-xrun -f myimage.bin -p /dev/ttyUSB0 -b 19200 -r pl2303

The -r option specifies one of the ways to reset board. For more info on board reset mechanism, please see Appendix A

Execute a chain of files without reset

~# rumboot-xrun -f init_ddr.bin -f test_ddr.bin -r pl2303

The -f option can be specified multiple times. Every image should exit with code 0 for the chain to move on. (See rumboot docs for more about this logic)

Log serial output to a file

~# rumboot-xrun -f init_ddr.bin -f test_ddr.bin -l uart.log

The -l option can be used to log output to a file

Using stdin

~# rumboot-xrun -f init_ddr.bin -I

The -I options makes the terminal bi-directional. E.g. You can not only see what the board sends you, but you can also type in some commands.

Auto-rebuilding project

~# rumboot-xrun -R -f example.bin

The -R options convenience option invokes automatically cmake --build example.all in the directory with the binary file. The target name is calculating by changing .bin to .all. This is hardcoded for 'rumboot' SDK for now.

Automatic stack trace decoding

rumboot-xrun provides a mechanism to decode runtime stack traces. To use this functionality, you have to place a .dmp file with disassembly in the same directory and with the same name as the .bin file

rumboot-xflash

Description

This tool allows you to quickly program different flashes attached to the target chip. It is done by uploading a precompiled stub that implements the programming protocol of the target flash media and accepts an xmodem payload. Pre-compiled stubs are shipped with rumboot-tools. For most chips these are heavily hacked u-boot spls. They run fully in internal on-chip SRAM, therefore don't care what DDR/SDRAM memories you have attached.

The tool provides users currently with two transports for programming: EDCL and SERIAL (XMODEM).

EDCL is generally faster, but requires a direct connection between you PC and the target board via ethernet. Some legacy bootroms only support EDCL for initial upload.

Serial (xmodem) is always present on newer chips. Some newer chips lack the edcl ip core (basis)

The transport for actual programming is serial by default, edcl can be selected by adding -e switch.

Writing will always be about twice slower than reading, since readback is usually integrated in the SPL doing all the work.

PRO TIP: You can just write the image to SD Card by popping it into your PC. That would usually be waaay faster.

rumboot-flashrom

Description

This tool works as a flashrom (http://flashrom.org) frontend/wrapper and allows you to read/write SPI flash chips that are (for some reasons) unsupported by rumboot-xflash. It works by uploading a stub that implements serprog protocol and attaching the flashrom to it. This tool can be used along with boards accesible via rumboot-daemon over the network.

Options

This tool works differently, compared to other tools. It accepts two sets of arguments:

rumboot-flashrom arguments. They are needed to configure port, reset, find & upload stub etc.
flashrom options. These are passed directly to flashrom utility. They do all the work.

In the example below

rumboot-flashrom -p /dev/ttyUSB1 -c basis -- --read img.bin

-p /dev/ttyUSB1 -c basis are rumboot-flashrom's options.
-- is the separator
--read img.bin are the flashrom options

rumboot-demon

Description

The idea behind rumboot-daemon is to allow access allow several apps/users to work with the same board over network. Basically it's a serial-to-tcp bridge that also handles board resetting and queues users for access to the board.

WARNING: rumboot-daemon lacks ANY kind of authorization or encryption and is supposed to be used in secure networks. Please, DO NOT EXPOSE IT TO THE INTERNET!!! You have been warned.

rumboot-daemon can theoretically work without the -r option, prompting the user to reset the board, but in real life this is pretty much useless.

See Typical Usage section for examples

When a user connects to rumboot-daemon, the tool powers on and resets the board, preloads it with any files specified on the commandline (if any) and redirects all serial traffic there. When the user disconnects, the board is powered off. If a second user connects when the board is in use, he/she would be placed in a virtual queue and wait until the board is available.

Options

usage: rumboot-daemon [-h] [-l LOG] [-p port] [-b speed] [-f FILE]
                      [-c chip_id] [-r method] [--apc-ip APC_IP]

Serial Port:      /dev/ttyUSB0
Listen address:   ['0.0.0.0:10000']
Please, power-cycle board
waiting for a connection

Once the daemon is working, you can connect to it on port 10000 with rumboot-xrun:

rumboot-xrun -f rumboot-basis-PostProduction-spl-ok.bin -p socket://192.168.10.1:10000

N.B. Remember to specify the correct IP address.

Start the daemon on boot using systemd, listen on a different port

Next enable and start the daemon

  ~# systemctl enable rumboot-daemon
  ~# systemctl start rumboot-daemon

Preloading an application before giving the user access to the daemon

Sometimes it's useful to initialize some external memories (e.g. ddr) or execute an application before allowing user access to the board. You can specify one or several applications using the -f flag

~# rumboot-daemon -c basis -p /dev/ttyUSB0 -r pl2303 -f ddr_init.bin
Detected chip:    basis (1888ВС048)
Reset method:     pl2303
Baudrate:         115200 bps
Serial Port:      /dev/ttyUSB0
Listen address:   ['0.0.0.0:10000']
Please, power-cycle board
waiting for a connection

The ddr_init.bin in the example above should initialize the ddr memory and return to bootrom with code 0. rumboot-daemon will send it to the board and only then redirect serial stream to the connected user.

Appendix A. Board reset methods

rumboot-xrun, rumboot-xflash and rumboot-daemon all accept the -r option that configures the way boards are reset. The following reset methods are available:

pl2303 (linux-only) - Uses PL2303 chip GPIO for power and reset control. The two GPIO lines of PL2303HXA should be connected to reset and power lines. Most RC Module's reference boards have this circuit. rumboot-tools will try to guess the correct device if more than one pl2303 device are connected.
mt12505 - Uses MT12505 board for power control. Internal RC Module's hardware. Don't use.
apc - Uses telnet-accessible APC Switched Rack PDU. Requires a set of options to be supplied:

  --apc-ip APC_IP       APC IP Address/hostname
  --apc-user APC_USER   APC IP username
  --apc-pass APC_PASS   APC IP username
  --apc-port APC_PORT   APC Power port

If you wish to implement your own reset method - look into rumboot/resetSeq

rumboot-combine

Description

rumboot-combine is a simple to tool to compose a chain of several image file. Since Rumboot V2 the rom loader can load a chain of applications, one after another from flash media. Different boot sources require different size alignment, so this app can handle all that. For basis this tool is also used to append the .ini configuration file to the image.

~# rumboot-combine --help
usage: rumboot-combine [-h] -i INPUT -o OUTPUT [-a ALIGN]

Typical usage

Combine several apps into SPI flash image

  rumboot-combine -a spi -i ddr_init.bin -i memorytest.bin -i uboot.bin -o spiflash.bin

  rumboot-combine -a 1 -i ddr_init.bin -i memorytest.bin -i uboot.bin -o spiflash.bin

Combine several apps into SD flash image

  rumboot-combine -a SD -i ddr_init.bin -i memorytest.bin -i uboot.bin -o spiflash.bin

Combine several apps into NOR flash image

  rumboot-combine -a physmap -i ddr_init.bin -i memorytest.bin -i uboot.bin -o spiflash.bin

Append ini to a chip config tool

  rumboot-combine -a ini -i tool.bin -i config.ini -o runme.bin

Combine images with custom alignment

  rumboot-combine -a 32 -i 1.bin -i 2.bin -o all.bin

Appendix B. Adding Rumboot V1 header to your app

The tool expects that your compiled binary will already have a valid header that has all required fields except for the checksums and data length. To to this, you have to add a single .c file to your project that will define the header structure.

The V1 is the initial header as implemented in 1888TX018. It's very basic, but may contain two entry points.

Your project should have the following C code that will put the header in your code.

    extern void entry0();
    extern void entry1();

    #define BOOTHEADER_MAGIC__BOOT_IMAGE_VALID       0xbeefc0de
    #define BOOTHEADER_MAGIC__HOST_IMAGE_VALID       0xdeadc0de
    #define BOOTHEADER_MAGIC__RESUME_IMAGE_VALID     0xdeadbabe
    #define BOOTHEADER_MAGIC__CORERESET_IMAGE_VALID  0xdefec8ed


    struct legacy_bootheader
    {
        uint32_t magic;
        uint32_t length;
        uint32_t entry0;
        uint32_t entry1;
        uint32_t sum;
        uint32_t hdrsum; /* Checksum of all previous fields. */

        uint8_t imagedata[1]; /* Image data. */
    } __attribute__((packed));

    static const __attribute__((used)) __attribute__((section(".header")))
    struct legacy_bootheader hdr = {
    	.magic		= BOOTHEADER_MAGIC__BOOT_IMAGE_VALID,
    	.entry0	= (uint32_t) &entry0,
    	.entry1	= (uint32_t) &entry1,        
    };

A typical lds script tht will place that header at the very top of IM0 SRAM would look like this:

MEMORY
{
    IM0 (rwx): ORIGIN = 0x40000, LENGTH = 0x40000
}

SECTIONS
{


.text :
{
  KEEP(*(.header))
  *(.rumboot_platform_runtime_info);
  *(.text)
  *(.text.*)
  *(.rodata)
  *(.data)
} > IM0

.bss :
{
  rumboot_platform_bss_start = .;
  *(.bss)
  *(.bss.*)
  rumboot_platform_bss_end = .;
  rumboot_platform_heap_start = .;
  . = . + 0xf000; /* 60k heap */
  rumboot_platform_heap_end = .;
  rumboot_platform_spl_start = .;
  . = . + 0xf00;
  rumboot_platform_spl_end = .;
} > IM0

.data :
{
    *(.data)
} > IM0

.rodata :
{
  *(.rodata)
  *(.rodata).*
} > IM0

}

Once you compile and link your app, run

rumboot-packimage -c -f file.bin

And it should do all magic, required to boot this image
