Hi,
I've got this board and it's giving me trouble.
It will not start because PP3V3_S0 only has 1.8V
When I measure resistance to ground, I get about 130 Ohms, while a good board has approx 1KOhm
Thing is 130 Ohms is too much to be able to get the bad guy to get hot enough to find it.
I've tried to inject 3.3V anyway, and didn't indeed find anything especially hot.
But after I did that and let the voltage run for a few minutes, I was able to see the board was sometimes booting and sometimes not. I connected a speaker to be certain and I did hear a chime.
Now, the next day, the board doesn't boot anymore.
I'm not quite sure what to do from here. I can't really consider removing all the stuff on the 3v3_s0 rail until the 130Ohms to ground goes away, there's just too much stuff.
So any suggestion would be more than welcome
