Hello everyone! It seems that I've bricked the FPGA somehow during kernel update (which actually didn't happen at all since the update process was not even started - there was a message that something wrong with my sd card).
After that I couldn't enter the update menu at all. Actually, the EZOS even doesn't boot. My GBA just shows own boot logo and that's it. Maybe my sd card has corrupted the contents of the FPGA or NOR... or SPI flash on the back side. I've started checking the SPI, but I can't find its original image anywhere.
I was able to create a dump from SPI, but it would be nice to have at least the checksum of the contents to verify the image is correct. And, it also would be really nice to have the pinout for the jtag interface on the board (don't want to de-solder the FPGA to check which points are connected even though I can)... I assume it goes directly to FPGA, since NOR should be connected to FPGA directly...
So any help is appreciated. Thanks.
