Using JTAG-lock-pick Tiny 2 as flashrom programmer

[mailmuncher mailmuncher]

Hello!

Thanks for flashrom!
Had a question about using "JTAG-lock-pick Tiny 2" (https://distortec.com/jtag-lock-pick-tiny-2/) as flashrom programmer. It is a FT232H based openocd jtag programmer so I figured I could use it like so:
$ flashrom -p ft2232_spi:type=232H -r dump.rom$ flashrom -p ft2232_spi:type=232H -w bios.rom
But the PID is not the standard FT232H of 0x6014 so I adjusted the 232H PID value in ft2232_spi.c to match: 0x6014 --> 0x8220. Then re-compiled and now flashrom seems to recognize the device. But still not able to read any spi eeproms.
Would be great to get any input on how I could make this work or things I could try.
ThanksVivek

Hi there Vivek, please share your connection scheme with us - maybe
something is wrong with it. Also, could you successfully flash with
another flashrom-supported programmer using the same connection
scheme?
