Hey Jon,
I had a chance to briefly take a look at this.
Kali 2022.3 worked and binded with our zymbit products following the same solution that was found here: Support for Kali Linux 2020.2b
Encrypting the sd card did not work for me. I found the error occurs due to a complaint on how the zymbit hook script is set up in the initramfs process. There may be something kali linux specifically looks for in the initramfs.
If you want to take a look at it yourself our encryption scripts are free to use and modify. Our encryption script can be downloaded via:
curl -G https://s3.amazonaws.com/zk-sw-repo/mk_encr_sd_rfs.sh --output mk_encr_sd_rfs.sh
You may also use this as reference from kali’s site to point you in the right direction: Raspberry Pi - Full Disk Encryption | Kali Linux Documentation
Thanks for your patience,
Eric
