Debugging Custom TX2i Carrier Board

Hi, I am trying to bring-up a custom carrier board for a Jetson TX2i. I have flashed the module with my custom firmware (after making all the changes recommended in the bring-up and adaptation guide) using the development kit. However, when I install the module in my carrier board nothing works. This is not surprising, there is always some amount of debugging when doing this type of stuff. My problem is I don’t know how to go about debugging. There is no display output on my carrier board, and the OTG USB port is not working, so I am not sure how to interact with it. I don’t even know if it is booting, at this point all I can do is monitor the power draw (~3.3 W at 12 V). Any advice on where to start would be great.

Use the uart console. Check how other posts doing over the forum and you will find it out.
