To follow up my post, Werner, or anyone else reading this :
My UART adapter was ordered, but the shipping lost its way to me. I have to place an order again.
The situation went better for a time without updating the kernel...
Then I updated to kernel 6.1.99 and the problem reappeared, now I'm stuck in this because I tried another kernel and it did not boot.
For this step, I had to reboot on the SD to the lastest I downloaded at the time of install and installed this version with the root to the nvme, and the bootloader to the SD. It booted, but then after updating to latest, showed no sata anymore.
I downloaded again an image under 6.1.99 kernel it worked, but still no sata.
I then tried the OMV image, but after configuration, modification of the keyboard layout and reboot, root password typed in every combination possible (regarding QWERTY or AZERTY interpretation of the keyboard input) did not work... It's a problem I already encountered while being sure to have typed the password correctly.
I tried also 6.12 images, but no boot (black screen)
Someone please help, I'm ok to pay for support (I already did it, but will be grateful to the one who will help).
