I am designing a custom carrier board for jetson nano module.
Currently I cannot boot up but I can get the log from the UART debug and see it keeps on restarting.
I already make sure the 5V to jetson nano and the PW_EN is stable.
While I’m inspecting the log difference between the jetson nano development kit and my customer carrier board I found there are some differences.
" pmic max77620 NVERC : 0x40
[0000.152] RamCode = 2
[0000.154] Platform has DDR4 type RAM"
The log from normal jetson nano developer kit board is RamCode=0.
I am also confused to find that the jetson nano have A02 and B01, and I also find information saying the jetson nano developer kit board is different with the jetson nano production module. Currently, I have the jetson nano developer kit and remove the SOM and put it into my custom carrier board.
I want to know whether the above is true and if I am following the schematic from DLC, which pinout it is referring to?
If I buy the new version which is B01 is it the same with Jetson Xavier pinout and the same with the carrier board schematic provided from DLC?
