Hello I have bought the relatively universal programmer and did the rev 2 mod on mine, I am running the latest FW at the moment and am I having problems flashing / reading from the board

I have a file called 1.bin which is 32Kb of random data, and another which is a dump from the Chip after I flash it

image

Reading the eeprom after writing to it reveals that only some of it has been properly burned.

20240926_192523

Is the setup of my programmer, I believe I have set the jumpers correctly.

Given that I can burn and read it, its not 100% dead is it?

log is
