![]() ![]() Xeltek in-system programming tools provide a convenient method for configuring microcontrollers and various serial devices. Obviously the Pi only outputs 3.3v via GPIO (the 5v feed can't be used if it will be fed back into GPIO) so this is the main limitation as far as legacy hardware goes. Some EEPROMs can be programmed in-circuit with ISP header cable, please refer to our ISP programming page for connecting the chip on target board to the programmer. I cleaned up the code I had wrote and dubbed the program PiPROM: The Raspberry Pi Xbox EEPROM Programmer. But I now had a nifty setup that would allow me to read and write the EEPROM from an xbox, whether it was still attached to the motherboard or removed. ![]() The main examples I've seen deals with 8 pin UEFI-based ROMs (SPI chips), so I'm not sure how versatile the application is - I have a model B Pi, which doesn't possess as many GPIO pins as the + model. Depending on the type of chip, connecting it to ground or to voltage will make the chip write data to a selected memory address (more on that later). There was no rejoicing to be had for my lost game saves. Apparently you can, and there are a number of guides on how to achieve it. I was playing with my Raspberry Pi the other day and wondered whether I could use it to program EEPROMs - I don't have a programmer (although I do have a bunch of LAN cards that could do it) so I thought this might be a cheap way to reprogram some ROMs. Thought I'd post up this discovery in case other people might find it useful. ![]()
