Just use a recommend pd supply.
I dont know where is the hint, i used several 20-30€ Power supplys.
In First use My nvme Samsung evo was not detected anymore after 8 Weeks working. So i bought a new PD supply (No PD cable) and the nvme is again working.
In Second, i flashed a new Bootloader and Original Back,nvme was again Not detected. (Tested on 3 different Sd with fresh Install radxa and armbian)… Not working.
In Third, i bought the original pd supply and emmc. Nvme was Not detected in this Case with new flashed radxa and armbian Images in SD.
In fourth, i flashed armbian on emmc. And all 3 Power supply working with detected nvme.
In every step i used the Same Bootloader and Images since the second step. Flashed with Rufus and dd twice.
I dont know what ist that.
