Hi,
I have a new RPi 400. When I boot it with the official alarm aarch64 image, an error "invalid bus width, error -22 wilst initialising SD card" occurs and the boot process is in an endless loop. With the armv7 image this does not happen. I also tried it with another SD card with an alarm aarch64 image which I took out off a ca. 1 year old RPi 4. Booting the RPi 400 from it resulted in the same error. In the older RPi 4, that card works nicely.
Seems that this is this bug. Thus it seems that the hardware of the current models and the current 64bit kernel do not fit to each other.
Did others here observe that bug as well? Any idea how I can circumvent it (except switching to the armv7 image, of course)?
Thanks,
mipi
