GFMPW-1 read compare FAILED
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?
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

Incorrect MFG value, expected 0x0456.
What's wrong now?
