Thanks for the help so far. Without this, the solution would be even more difficult.
I'm going to call i
mx7d-SOM-one the one that changed two capacitors, it worked for 3 hours and stopped again.
I will call i
mx7d-SOM-two the one that changed the main ic. It shows no sign of life. Not 19 degrees Celsius, nothing.
The problem now lies in the difference in
measurement of the resistors. I need to find them (with your help) in the
schematic (pdf in the link below) and confirm the problem.
As foto01 from the link below, on the resistors marked in
yellow, on the i
mx7d-SOM-one. the values vary from
3.3v to 2.6v on one side and the other of the resistors. In the
green part of 0.748v and the r
ed part of 0.874v.
in the
imx7d-SOM-two the resistors marked in
yellow do not vary from side to side of the resistors, always givin
g 3.3v. BUT, both in the
green part, as in the
red part, they give
0.000v.That is, I need to study the schematic. How do I find the aforementioned resistors in the file pico-pi-imx7-rev-b1-37-53-2-5.pdf which is in the link below?
