Hi,
I designed a custom board jetson-nano I think, I have problem with hdmi output.
I Have two modules
one is p3448 180-13448-DAAA-B01
when I plug this module to my cutom board, I get this screen
second module sd card version p3448 180-13448-DAAA-A02. I finished its installation on devkit p3450. And It works on devkit, But not on my custom board. I get black screen.
My schematics
I referenced antmicro and devkit while designing.
This is not related to HDMI. Sharing a display schematic does not help.
It is triggered by some unknown pin/button detection during boot process and cause that.
Dump your serial console log from UART and it will tell.
Something duplicated with your issue.
Thank you for yor respond
I figured out that
p3448 180-13448-DAAA-B01 and p3448 180-13448-DAAA-A02 have different pinouts.
that’s way I couldn’t make a02 work.
I will look that
