Hey

i have a v1.3, x3(pin header install) and i shorted the molex cable which caused it to frag.

I have checked all the solder joints and checked for splashes and visual damage and nothing, it look perfect.

Here are the voltages i get:

Pin | Name voltage My voltage
1 | LCLK | 0.2V | 0V sad.gif
2 | Ground | 0V | 0V
3 | LFRAME |0V(on 1.3)| 0V
4 | no pin |-----------|-----------
5 | LRst | 3.3V | 0.17V sad.gif
6 | VCC5 | 5V | 5.01V
7 | Lad3 | 3.3V | 3.21V
8 | Lad2 | 3.3V | 3.21V
9 | VCC3 | 3.3V | 3.24V
10 | Lad1 | 3.3V | 3.21V
11 | Lad0 | 3.3V | 3.21V
12 | Ground | 0V | 0V


Any clue whats wrong

Any help is apreciated

Cheers

the first one is likely not an issue.
Try measuring the voltage on reset while it is trying to boot up.
once it's fragging the reset line almost always goes low and stays there.

i checked pin 5 (LRst) and when booting it flashed up 2.7 on my multimeter.
i guess thats what its meant to be?
