pinephone pro boot: kernel image not aligned on 64k boundary

[kmerfeld]

Hello, I was trying to install the custom modem firmware (https://github.com/Biktorgj/pinephone_modem_sdk) on my pinephone pro,
but I think I borked something. whenever I boot I get something like https://pastebin.com/q6ksLzih

This happens on both emmc and sd card, though I wiped emmc over tow-boot's USB Mass Storage mode at some point.

I've tried booting with postmarketos and manjaro, and get similar results. Any pointers on what I can do?

Something similar happened for me, although not from flashing modem firmware. I just flashed the Plasma Mobile postmarketOS image for pinephone pro (20220803...) from an SD card, and it installed fine. Booted it, and set my encryption password and login passcode. Seemed to be working alright. Set it down for the night, and in the morning, the battery must have died, so I charged it, and it boot looped (known issue I understand), and then it went dark; no boot loop. Connected with the 3.5mm audio-serial cable, and found this.

Update: It seems that the "kernel image not aligned" may be unrelated to my problem. Seems that my PinePhone Pro battery was related to my boot-loop problem. I swapped my original PinePhone battery into the Pro, and it stopped boot-looping, and just worked. As a sanity check, I tried booting my original PinePhone with the Pro battery, and it did not boot. The whole way, I saw the "kernel image not aligned" message fly by during boot, but it hasn't seemed to cause any problem that I have seen yet.
