## MTA1-USB-V1 and TP-1 programming board firmware
The programmer boards are running a custom firmware developed by
Blinkinlabs. The source code for this firnware is available on
Github: https://github.com/Blinkinlabs/ice40_flasher
There is also a pre built firmware binary available for the
programmer board:
https://github.com/Blinkinlabs/ice40_flasher/tree/main/bin
The TP-1 programming boards runs a custom firmware developed by
Blinkinlabs. Source code for this firmware can be found at
[hw/boards/tp1/firmware/](../hw/boards/tp1/firmware/). There is also a
pre-built firmware binary at
[hw/boards/tp1/firmware/bin/main.uf2](../hw/boards/tp1/firmware/bin/main.uf2).
To update the firmware on the programmer board, either build the file
"main.uf2", or download the pre built file to your host computer.
Then do the following:
`main.uf2` (more instructions below), or get the pre-built file to
your host computer. Then do the following:
1. Disconnect the programming board from the host computer
2. Press and hold the "BOOTSEL" button on the RPi2040 sub board on
the programming board
2. Press and hold the "BOOTSEL" button on the RPi2040 sub-board on the
programming board
3. Reconnect the programming board to the host computer
4. Release the "BOOTSEL" button after connecting the programming
board to the host. The board should now appear to the host as a
USB connected storage device
5. Open the storage device and drop the firmware file ("main.uf2")
into the storage device
4. Release the "BOOTSEL" button after connecting the programming board
to the host. The board should now appear to the host as a USB
connected storage device
5. Open the storage device and drop the firmware file `main.uf2` into
the storage device
The programmer will update its firmware with the file and restart
itself. After reboot the storage device will automatically be
disconnected.
