--fw-tar FW_TAR Path to the firmware tarball
tt-flash --fw-tar <firmware tar file path goes here>
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 are licensed and distributed independently of tt-flash, as this is just the system to deal with the actual flashing of the images.
