Hi. I’ve faced unusual problem and for now can’t solve it. Mb someone had similar experience and can share the solution.
I’ve installed Zymkey4 as mentioned in official doc (Quickstart - ZYMKEY4 |).
Everything works fine.
Then I add camera for my application. It works fine and detected.
Then I do full rootfs encryption just like said in the doc (Encrypting Root File System with Zymbit Security Modules |). It works fine and now system boots only with zymkey.
But camera is not detected anymore (it worked fine before encryption).
$ libcamera-still --list
No cameras available!
And I can’t make it work. It’s not detected anymore though all overlays mentioned correct in config.txt file.
I think it’s some kind of i2c problem because camera slot shares i2c bus with zymkey, but I checked before encryption and both camera worked fine and zymkey worked fine (was detected and passed basic tests) and by specs i2c can share multiple devices on the same bus.
If some had similar problem please help. Or if you know what it is.
If some files needed to provide to help just let me know plz.
Thanks beforehand guys.
