I have the same problem with my gp32 blue, is it possible to get a link on how to build a jtag cable and try to program the bios again? thanks and regards
Very incomplete, most of the time you just need a Jtag adapter to reflash a corrupted image. If the eeprom ever actually fails you need replace and that is what you are showing.... still need to show the part where you actually flash that eeprom
Sorry but it's not a tutorial, but you can take a look at the repair log, the link is in the description. This time lapse video has been made just for fun it's not intended to be a repair guide at all.
@@arcadefraidi Did you add this link ? i missed it initially Sorry if it was there from the beginning. I have fixed many of these units. The only thing i may add is that quite often the eeprom is not dead but the FW is corrupted, a tutorial on how to simply build a Jtag cable and re-flash the FW would propose a more simple procedure
@@romaintrilling7822 you are right, using a JTAG cable could be an easy way to repair these units. But I didn't know why the flash has been corrupted, if the damage was due to a software corruption or an hardware fail. So to avoid the risk the flash could fail again my choice is to replace it anyway. I repaired two GP32 units one flash seemed to be good after reprogramming and one was bad. So even a statistically fifty-fifty chance is not enough for the units I fixed.

@@arcadefraidi Yep, AT49BV040 appears to be a more reliable component. I have not yet seen a failure with those.
