Merci Vincent, j'ai eu un mince espoir mais sans succès.
(Thanks Vincent, I had a moment of hope but unsuccessful).

I have ordered a new card from ElecBee which confirms me they'll send it soon. I think what was the cause of my previous mistakes/brick was that I erased the partitions from within the Linux OS out of fatigue, which must have deleted
the boot and system partitions.

So, just to be clear (@Kettenis):

If I simply wipe the emmc the clean way using upgrade_tool ef command, I
should be able to boot an OpenBSD 7.8 miniroot SD “patched” with the uboot
from u-boot-aarch64 package, and install it. ... right ?

(upgrade_tool is the closed source version of the tool from Firefly which
rkdeveloptool is the open source version of)

Thank you

Bonjour Sylvain,

J'ai eu qq chose qui ressemblait un peu, la carte (pas le même modèle)
avait l'air brickée...
J'ai dû insister un peu avant de trouver la bonne combine, mais ça
valait le coup...

Voilà mes notes sur le sujet:

If you wipe your emmc, you may render your board unbootable (symptom here
was no output on serial console at all at poweron)

To restore it to a bootable state, you need to put back the SPL loader
on the emmc.

You will need to use pine64 rkdevtool to do so.

Plug download usb cable

Start the board in maskrom mode, by holding the maskrom button then power it up.

Test that it is properly detected:

./rkdeveloptool list
DevNo=1    Vid=0x2207,Pid=0x350b,LocationID=501    Maskrom

Then restore the SPL loader on emmc:

SPL_LOCATION=... (maybe from: https://github.com/rockchip-linux/rkbin.git)

cd .../dev/repo/upstream/rkdeveloptool
./rkdeveloptool boot ../${SPL_LOCATION}/rk3588_spl_loader_v1.08.111.bin
./rkdeveloptool erase-flash
./rkdeveloptool upgrade-loader
../${SPL_LOCATION}/rk3588_spl_loader_v1.08.111.bin
./rkdeveloptool reset

J'espère que ça pourra aider.
