So I eventually reflashed the board and I can access it now. However, the desktop looks a bit “weird”. For instance I only have 3 buttons on the left side menu. Plus, I also see a purple arrow on each desktop icon. I’m also seeing the following warning when booting up “Test key is used” ("Test Key is used" can be removed? - #3 by kayccc). Also I find a bit weird that when I flash the image (~1.5 GB) and I install CUDA (~1.5 GB), the internal disk becomes full. I can’t install anything else.
I checked Aetina website and they don’t provide any sdk (bsp).
I would like to know if this is normal to have ~16 GB of ubuntu+CUDA on the internal disk. If so, how can I put a sd card to work with the board? I noticed with the flashed image version the card is not detected. I have other nvidia where the sd card is recognized.
