I downloaded Armbian_25.5.1_Nanopi-r6s_trixie_current_6.12.32_minimal.img.xz and used unxz to uncompress it. Then I wrote it to a flash drive using:
sudo dd if=Armbian_25.5.1_Nanopi-r6s_trixie_current_6.12.32_minimal.img of=/dev/rdisk4 bs=4194304 status=progress
sync
When I put the SD card in the slot, the heartbeat LED runs, the keyboard initializes, the LED light for the connected LAN lights green, but I get nothing on the monitor (HDMI). The SD cards are amazon basics 64GB Class 10 U3 A2 cards. I tried two different cards and got the same results. I just tried Debian from FriendlyElec, and that worked using the same cards and method, and that worked. Is there a trick to getting these images to work?
I'd much prefer to be on the mainline kernel with Trixie (which I know will be released soon). Please advise.
