GFMPW-1 read compare FAILED

[gonsolo]

I try to test my GFMPW-1 chip that I received last week.

Connecting the board via USB results in the following dmesg (with a harmless warning, I believe):

[ 9. Sep 11:55] usb 5-1: new high-speed USB device number 3 using xhci_hcd

Building the firmware via make clean hex in chipignite/blink works, I had to adjust the Makefile to:

TOOLCHAIN_PATH=/home/gonsolo/bin/
TOOLCHAIN_PREFIX=riscv64-unknown-linux-gnu
ARCH=rv32i_zicsr

But flashing the chip fails with:

gonsolo blink:sudo make flash
python3 ../util/caravel_hkflash.py blink.hex
Success: Found one matching FTDI device at ftdi://ftdi:232h:5:3/1

Any idea what went wrong?

[gonsolo]

After playing around with it for a while nothing works anymore:

Success: Found one matching FTDI device at ftdi://ftdi:232h:5:3/1
Caravel data:
   mfg        = 0000
   product    = 00
   project ID = 00000000
Incorrect MFG value, expected 0x0456.

What's wrong now?
