E1xxxxxx = XDPE phase pwm controller error VRM 2 phases
E2xxxxxx = XDPE phase pwm controller error VRM 6 phases
I would check the XDPE controller and the VRMs at the both phases.
I haven’t performed the UART read yet. I’m currently using a known-good dump from a 1215B 61G, while my board, which is missing the BIOS chip, is a 1216A 61G. Do you think this could be the problem?
That said, I’ll get a dump for a 1216A 61G...
Be Sure you using RTD2175P NOT other incompatible model, and since EDM044 board has significant change on the HDMI ic circuit, 0.9v line is likely only related to the "RJ=" CHIP(RT9048AGQW)
There are two 0.9V lines. One (neon green marking) generated from the 1.8V by a little 5 legged converter and one (light green marking) 0.9V by a qfn chip 'RJ='.
EDIT: It is the ciruit for the MN864739 HDMI chip. The layout for the newer...
Maybe I got it wrong, but you should be able to get the bd permanent* unpatch with y2jb - p2jb - bdj_unpatch.elf chain.
(*an update will remove the unpatch)
The switchable 1 Ohm resistor should be only present at a edm-03x board.
Position A for 69GG is connecting the 3.3V_SS_PG1 to southbridge pad 4C.
Position B for 61GG is grounding this line.
At other board versions, I don't know if a 69GG will...
And do you have an answer to the question? :)
If I restore the Y2JB backup on my PS5 slim with manually paired drive, does the restore process unpair the disc drive?
