Hello, i've Willem Eprom PCB5.0b with which i'm tring to flash the rom into chip SPI 25P10V6 (ST)
After i write it i get always error at 0x000000 Chip=0x82 Buffer=0x79
I don't understand why??
I also disabled write protect pin 3 pulling it to Vcc ( pin 8 ).

I posted for you the original rom (which i want to write) and the bad rom (which is how the Willem programmer writes the original rom on chip 25p10V6)!!

Original ROM:

This is how the eeprom writes it into the chip:

Please can you help me programming this chip correctly?
I don't have any problem with 25P40 chips but with 25P10V6 it's impossible.
Could be a Willem bug?

This is my post about it with a lot of pics:

Thank you.

Not tested your chip. I had equal 25P10 , but it works as 25P10A- autoselect return id man 0x20, chip 0x2011. Probably revision A was not readable from chip body.
