tt-flash 3.4.1

Utility to flash firmware blobs to tt devices

tt-flash

This is a utility to flash firmware blobs to tenstorrent devices.

Official Repository

https://github.com/tenstorrent/tt-flash

Getting started

Regardless of install path (straight pip or git clone for development)

Install Rust (if you don't already have it)

Note: This is only needed if you haven't already installed luwen

Using Distribution packages (preferred)

• Fedora / EL9:
  sudo dnf install cargo
• Ubuntu / Debian:
  sudo apt install cargo

Using Rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"

(Optional) Virtual environment

Virtual environments allow Python to create a self-contained area where it can install things and deal with it's own library pathing. If you aren't doing this as a system level install a virtual environment is recommended.

python -m venv venv
source venv/bin/activate

To install without git (non-development):

If you just want to install tt-flash, and not do any development, you can just use pip (with or without a virtual environment) to install a public version.

pip install git+https://github.com/tenstorrent/tt-flash.git

Note: if you fork the repository please fill in the appropriate accessible URL above to install tt-flash

tt-flash is now installed

To Build from git (development):

Clone the repository

If you haven't already cloned the repository you are reading this from clone it now, this will vary depending on where this repository is at. The official public repository is at https://github.com/tenstorrent/tt-flash

git clone https://github.com/tenstorrent/tt-flash.git
cd tt-flash

Building the repository

pip install .

or for users who would like to edit the code without re-building

pip install --editable .

Help text

usage: tt-flash [-h] [-v] [--sys-config SYS_CONFIG] [--no-color] [--no-tty] {flash} ...

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit
  --sys-config SYS_CONFIG
                        Path to the pre generated sys-config json
  --no-color            Disable the colorful output
  --no-tty              Force disable the tty command output

command:
  {flash}

usage: tt-flash flash [-h] [--sys-config SYS_CONFIG] --fw-tar FW_TAR [--skip-missing-fw] [--force] [--no-reset]

optional arguments:
  -h, --help            show this help message and exit
  --sys-config SYS_CONFIG
                        Path to the pre generated sys-config json
  --fw-tar FW_TAR       Path to the firmware tarball
  --skip-missing-fw     If the fw packages doesn't contain the fw for a detected board, continue flashing
  --force               Force update the ROM
  --no-reset            Do not reset devices at the end of flash

Typical usage

tt-flash flash --fw-tar <firmware bundle file path goes here>

Grayskull Note:

If you are using a Grayskull based card, the card itself does not have an on-board reset mechanism, and you will need to reboot to have the new firmware apply.

Firmware files

Firmware files are licensed and distributed independently of tt-flash, as this is just the system to deal with the actual flashing of the images. You can find the firmware files in a seperate repo https://github.com/tenstorrent/tt-firmware.

Example output

This is an example of what you can expect the final output to look like on a system when not needing an update

$ tt-flash flash --fw-tar ~/work/build-combine-flash-pkg/fw_pack.tar.gz

        Could not find config in default search locations, if you need it, either pass it in explicity or generate one
        Warning: continuing without sys-config, galaxy systems will not be reset

        Stage: FLASH

FLASH SUCCESS

And when forcing an update with --force

$ tt-flash flash --fw-tar ~/work/build-combine-flash-pkg/fw_pack.tar.gz --force

        Stage: FLASH
                Sub Stage FLASH Step 1: Grayskull[0]
                        ROM version is: (80, 9, 0, 0). tt-flash version is: (80, 9, 0, 0)
                        Forced ROM update requested. ROM will now be updated.
                Sub Stage FLASH Step 1: Wormhole[1]

                        Board will require reset to complete update, checking if an automatic reset is possible
                                Success: Board can be auto reset; will be triggered if the flash is successful
                Sub Stage FLASH Step 2: Grayskull[0] {e150}
