Did you create and enable the edid.cpio initrd as well?
getedid create will all do this automatically but braviaedid.bin looks like you set this up manually.
No, I did not - no idea how and why should I have done it. I copied the edid from a pi zero which was able to use the tv, and this firmware load etc worked a week ago.

Hi!
I'm trying to use my Pi5 on an old bravia television, and I managed to make it work by loading the edid from the kernel command line. But this stopped working now.

For my untrained eyes this looks like a wrong order of things. Do my eyes deceive me?
The file is there:
pocok:~ # ls /storage/.config/firmware/
braviaedid.binThe fixup parameter does nothing useful, the output is the same without it.
Thanks in advance.
