So maybe there are multiple issues (or multiple different sets of symptoms extending from the same underlying issue) which might show up on some boards but not others

You’d mentioned earlier in this thread that you were seeing problems in the bootloader. So your board is failing to make it past U-Boot? That is interesting. My board had no problem using the unmodified copy of U-Boot supplied with the Armbian image; instead, I ran into trouble inside Linux itself, while the initrd was looking for the root filesystem.

Alrighty, so I followed all the necessary steps, such as burning the latest Armbian image into an SD card and then modifying boot under a Linux environment, however, despite following them, I still can’t boot the board at all.

You had previously captured the progress of other failed boot attempts using a serial cable. How do the printouts you see with my proposed changes compare with what you saw in your other attempts?
