I am unable to detect the SD card on the A203 carrier board.
I am using the Jetson TX2 NX module, and the Jetpack as provided by the nvidia sdkmanager.
What else should I do?
Are there custom dtb files to make the board work with this carrier?
It did not work for me sadly, the SDK manager is failing to flash on the jetson. Seed has a really bad customer service and almost no documentation on this thing.
Try flashing via command line instead. I was having a similar problem (could not get sdk manager to flash 4.6 to my tx2 nx) and using command line instead solved the issue.
I got to work flashing the Nvidia SDK as it comes.
I tried the command line method which worked better most of the times.
Then I mounted the sd card following this post Installing an NVMe SSD on Nvidia Jetson Xavier | Medium.
