ABHT: large diff #563

Closed caden3ds closed 3 months ago

caden3ds commented 3 months ago

I installed the wifi chip and clock generator using Voultars tutorial, but whenever I try to change resolution in the first menu, I get "GBS board not responding!". Every other settings seems to work fine, for example when I use the picture control settings I can see it move. I do get a signal but it seems blurry and noisy with white pixels. What should I do?

caden3ds commented 3 months ago

I set Cycle SDRAM to 129Mhz and now the noise is gone, but I still need help with changing resolutions

caden3ds commented 3 months ago

Tested for continuity and everything seems fine, does anybody know what would it look like if the GBS8200 wasn't in debug mode? I think that might be it since I might've broken the pads for the debug mode

caden3ds commented 3 months ago

Reflashed with the correct board instead of the default one but it didn't change anything

caden3ds commented 3 months ago

Tried to resolder the debug pins and it looks like the ground is 100% broken, is there any other way to put it into debug mode?

ramapcsx2 commented 3 months ago

Hey, there is no debug mode. Maybe you're thinking of the debug pin signal that has to be soldered?

Yeah this thing at 26:19 https://youtu.be/1AVXhiTlmgo?si=wKLb6qSk_w4Qr3lJ&t=1579

schematic I soldered it to pin 37 seen here, and it works but now I have no signal and it says "ABHT: large diff" in the console

caden3ds commented 3 months ago

The error only shows when the clock generator is enabled

caden3ds commented 3 months ago

Also get "sync skipped ofr wrong: 111.16" and "Error: trying to tune external clock frequency while clock frequency uninitialized!"

caden3ds commented 3 months ago

Rewired the clock generator and I think its working? Rebooted with clock gen enabled and it seems to be fine
