I have a Boxer 8250 AI (NVIDIA Jetson Xavier NX AI@Edge Fanless Embedded Box PC, 5 GbE LAN Ports | AAEON BOXER-8250AI - AAEON) and flashed a Nvidia OS through Nvidia SDK on it. In the Boxer 8250ai is a Nvidia Jetson NX included. I used the official instructions to flash the operating system (Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation). So far so good, however I now face the problem, that the physical SD card reader is not detected. As the eMMC is per default nearly full (90%) I really need the extra space of the SD card.
I already found some posts about SD card problems with the Jetson Xavier which state that dtb files need to be adapted. I am totally new to such a depth of OS and I do not know, which dtb file I would need to adapt and what exactly is needed to do so. All posts I found where about self created custom OS and did not helped me to solve my issue (maybe I missed an important point). Nevertheless, I wonder if there is an easier way to get access to the SD card (maybe through installing a driver or something similar).
USB, HDMI and Ethernet ports all work properly, only the SD card reader is not working.
So to come to concrete questions:
- How can I get my OS to find the SD card?
- Is it required to adapt .dtb files or is there another way?
- Are this problems maybe related to the L4T (R32.7.1) or Ubuntu (18.04) version?
