I used to be able to read the chip on my Raspberry Pi.
I got a ch341a reader from the links above. I get a red light to show on the ch341a reader and a red light comes on on the motherboard, but I still can't read the chip.
Here's my error:
sudo flashrom -p ch341a_spi -r firmware-1.bin
flashrom v1.2 on Darwin 20.4.0 (x86_64)
flashrom is free software, get the source code at https://flashrom.org
Calibrating delay loop... OK.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.
I've also got this:
libusb: info [darwin_claim_interface] no interface found; setting configuration: 1
libusb: error [darwin_claim_interface] interface not found
Failed to claim interface 0: 'LIBUSB_ERROR_NOT_FOUND'
Error: Programmer initialization failed.
