camera firmware problems

[tomog]

I am experiencing a similar issue. Here is the dmesg of my NixOS machine, which has Martijn's autofocus patch and firmware.

$ journalctl -k | grep ov56

This did once work on this phone, but it has stopped working. I am unaware of any meaningful changes in my system since then.

I am running Megi Linux 5.13.

Each time I open Megapixels, I get new dmesg output starting with "firmware upload success" and ending with "ov5640_set_ctrl_focus: no autofocus firmware loaded".
