I'm pretty sure I've seen this error from a flaky control board before, so it might be worth trying another control board.


The 1.8V for each voltage domain is supplied by a regulator shown in the photo below, and then it is transmitted through each chip. The schematic in my previous post shows the pinouts for the regulators, and the photo from my previous post shows where the voltage can be measured at each chip. I have not worked on a T17+, but on other miners there is 2nd 0.8V regulator near the other side of the board that generates the 0.8V for the chips on that side of the board for the same voltage domain.
