Probably dead, yes. It looks like it is in read-only mode, so you cannot even erase it. Unfortunately for you, the way I designed the armbian boot requires either an empty flash or an installed u-boot that boots from sdcard first. You have three options: 1) hack the armbian boot using the multitool bootloader, but I don't suggest doing so because updates may overwrite the changes 2) remove the eMMC phisically, desoldering it 3) short the eMMC clock pins permanently, similar to what you would do when you want maskrom mode. The board will then always boot from sdcard. See the unbrick paragraph in the first post for some instructions.

THANK YOU so much for this effort. I no longer regret buying an OrangePi RV2!

There was a successful test with Debian Forky in RK3566 I saw some progress and success in the last 2 days. Someone made compiled ffmpeg 8.0+v4l2request and made it work in Debian Forky... which also carries ffmpeg 8.0 https://github.com/mpv-player/mpv/pull/14690#issuecomment-3500141427 Does this mean that I need to use Debian Forky too? (I was staying with Debian Bookworm because H264 hwaccel only worked there) References: https://code.ffmpeg.org/Kwiboo/FFmpeg/src/branch/v4l2request-v3 https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20847 https://tracker.debian.org/pkg/ffmpeg

How do you power the bananapi m1? It has 2 microUSB connectors.

Good evening. I spoke too soon. I wrote this: Armbian_23.11.1_Bananapi_bookworm_current_6.1.63.img but it doesn't support SATA either. Even if anyone has another idea or a working BPI M3 with SATA, I'd still be grateful for any suggestions.
