Pinecil boot logo flashing

[crc-32]

Didn't see any info on how to do this, correct me if it's somewhere I've not found or any of the steps are unnecessary, but I managed to flash a boot logo with the following:

• python3 img2ts100.py input.png logo.hex
• riscv-nuclei-elf-objcopy -I ihex -O binary logo.hex logo.bin
• dfu-util -d 28e9:0189 -a 0 -D logo.bin -s 0x0800f800

I would add this to the wiki but I don't think just anyone has access, and the repo docs just point there.

How did you do to flash the firmware file?
I used
sudo dfu-util -d 28e9:0189 -a 0 -D Pinecil.hex -s 0x08000000:mass-erase:force

but while the image seems to have been flashed correctly, it doesn't boot.

Ah, yes I will need to document this somewhere

The first command is correct, you need to flash it without the mass-erase after flashing the normal firmware.

If you include the mass-erase you will erase the firmware!

You can reflash using the latest bin file from the master branch artefacts to get the firmware back.

From my testing I don't think dfu-util takes hex files though (they are just considered binaries and soft brick the iron) so be sure to flash the binary not the hex file, which is likely why it didn't boot the first time you tried

I'll try right now, I assumed it was .hex based on the file Ralim provided at #730 (comment)

EDIT: Yup it's working :)

I'm not sure, but it didn't work for me until I converted it

What's the interest behind providing the .hex and .elf in addition to the .bin ?

[crc-32]

The compiler produces the .elf, it's then converted to a .bin and then I assume it's also converted to a .hex as the ts100 is able to use that file format, so regardless of what target you're using it produces that file too.

I can confirm the boot image flashing works: I modified the TS100 picture to look more like the pinecil and then uploaded it, here is the result:

Noting I did throw this in here
And put flashing docs here
