Hi,
i’m having trouble getting Zibkey4 to work with Pi5 8Gb latest OS with latest updates Bookworm (latest), i2c enabled using raspi-config:
ls -l /dev/i2c*
crw-rw---- 1 root i2c 89, 0 Mar 4 15:14 /dev/i2c-0
crw-rw---- 1 root i2c 89, 1 Mar 4 15:14 /dev/i2c-1
crw-rw---- 1 root i2c 89, 11 Mar 4 15:14 /dev/i2c-11
crw-rw---- 1 root i2c 89, 13 Mar 4 15:14 /dev/i2c-13
crw-rw---- 1 root i2c 89, 14 Mar 4 15:14 /dev/i2c-14
lrwxrwxrwx 1 root root 6 Mar 4 15:14 /dev/i2c-4 → i2c-11
Zibkey4 is in Dev mode, so im reusing it for every test install: If im using “blank” Pi5 with nothing, but a plain OS installed on it, then everything works OK and test scripts are completing fine.
However, if i then install Arducam drivers with settings required by Cam Array HAT (IMX519 Quad Cam) and also OLED display drivers (display connected to an SPI bus and uses Adafruit Blinka library) then test scripts for Zimkey4 are failing to complete with:

I also tried to first encrypt the disk and then install drives, then Pi5 will fail to boot.
Can you suggest a solution?
thanks,
