Hello, I'm looking to read a ST9040 PLCC68 chip but I don't know if I can do it with GQ-4x4 or some other tool. I looked on the internet and I can not find anyone in the same case as me. You have to unsolder it and use a plcc68 adapter (but I don't believe this exists for gq4)
or you have to read it in jtag but I don't really understand the ports used in the datasheet.
Thank you

It's not JTAG, it's SPI.
