Troubleshooting • Re: CM4 with Waveshare NANO-C - no boot

No, don't turn on secure boot - I was wondering whether you had already done that from the error message. I suspect the eMMC has failed, it all looks odd.

Turning on secure boot but not setting the key or losing the key bricks the device - it's not recoverable. Not something you can usually do by accident unless you have been playing with setting OTP bits.

Do you have a CM4IO board you can try, or a fresh CM4?
