Last week installed Armbian for the first time on my Pinebook Pro that was basically bricked from Manjaro. Everything worked great! Audio is a little weak, but will look into that later.
Today I pulled down the 25.2.1/6.12.16 update. On booting in Grub, I now get a message "Loading Device Tree Blob...", followed by "Error: not a regular file Press any key to continue". The boot then continues after a bit, and system seems to work fine from a user perspective after that (posting this from the machine). But there are some rockchip-pcie, rk3399-dmc-freq and brcmf errors in the armbianmonitor output (attached url) .
I'm an Armbian noob, so dunno if the errors were there on the previous version. The 25.2.1 install re-wrote the grub entries so I don't have the previous kernel to boot into to do any debugging, but it used to boot cleanly before the update. Wondering if there is a known situation here, before I dig into the whole dtb thing. Thanks!
