I'm trying to flash my GFMPW-1 chip sent to me last week. First, it nearly worked:
```gonsolo blink:sudo make flash
python3 ../util/caravel_hkflash.py blink.hex
Success: Found one matching FTDI device at <ftdi://ftdi:232>h:5:3/1
Caravel data:
   mfg        = 0456
   product    = 20
   project ID = 1801a030```
After playing around a bit this happens:
```gonsolo blink:sudo make flash
python3 ../util/caravel_hkflash.py blink.hex
Success: Found one matching FTDI device at <ftdi://ftdi:232>h:5:3/1
Caravel data:
   mfg        = 0000
   product    = 00
   project ID = 00000000
Incorrect MFG value, expected 0x0456.```
What happened? And is there anything I can do?

And at <https://github.com/efabless/caravel_board/tree/main/firmware/chipignite#readme> there is a link for installing a toolchain for Linux: <https://github.com/riscv/riscv-gnu-toolchain>
Going to the latest release (2024.09.03) there are dozens of assets? Which one should be used? <https://github.com/riscv-collab/riscv-gnu-toolchain/releases/download/2024.09.03/riscv32-elf-ubuntu-20.04-gcc-nightly-2024.09.03-nightly.tar.gz|riscv32-elf-ubuntu-20.04-gcc-nightly-2024.09.03-nightly.tar.gz>? risc64? elf or glibc? gcc or llvm?
