As I understand it, you can make a pretty efficient EEPROM burner from a Teensy 2.0++
In fact, I just used one to program some NAND flash chips to downgrade a PS3 two days ago.
Anyway, since my 3 PS3s are all downgraded now, I have no real use for the hardware anymore, but I just remembered that I have a GQ-4X that struggles to program anything that isn't a standard AMD EPROM (god help you if you try to do an PSOP44 EEPROM).
So, I still have all my sockets (TSOP48 and PSOP44), and I want to make my Teensy into a programmer to deal with these less cooperative flash chips.
Where can I learn about how to do this, or better yet, has someone already invented this wheel and maybe I can be directed to a hex file for my teensy?
