Kkorsar86 replied to the thread PS5 Pro BLOD - UART codes 808C4F90 and C0020303. USB-C issue?.Thanks for the maps! I just checked all the measurements around both ICs, and everything looks totally fine. The values are very close to your sheets, just minor differences due to board variation. Also, after re-testing the isolated bus, I am...

Maybe this both maps may help to find the issue. -

808C4F90/3790 can point to a peripheral init or power sequence issue, but I would not assume USB C immediately. C0020303 is often secondary when something earlier in init hangs. Before removing S2MMC or the TUSB mux, check the I2C lines first...

Kkorsar86 replied to the thread PS5 Pro BLOD - UART codes 808C4F90 and C0020303. USB-C issue?.Thanks for the great advice, lifting the series resistors instead of desoldering the whole IC was a lifesaver!Before pulling them, I checked the SDA/SCL lines to ground on an unpowered board, and they measured totally fine at around 9k Ohms. I...

Kkorsar86 replied to the thread PS5 Pro BLOD - UART codes 808C4F90 and C0020303. USB-C issue?.Any thoughts on this? Just to move forward with diagnostics, can I safely desolder the S2MMC01X01 chip or the TUSB44 muxer to see if the error code changes? I want to check if removing one of them releases the I2C bus and clears the 808Cxxxx...

Kkorsar86 posted the thread PS5 Pro BLOD - UART codes 808C4F90 and C0020303. USB-C issue? in Sony PlayStation 5.Hi guys, I have a PS5 Pro (VSM-010) stuck on BLOD. UART gives me these codes: 808C4F90, 808C3790, C0020303, 80000009. All APU power rails are fine (around 0.9V), no shorts in the VRM area, and the board warms up evenly. Based on the attached...
