Issue or Suggestion Description

After the utility ran successfully, I'm trying to call atcacert_read_cert but I'm not sure what cert_def to pass it. I tried running cert2certdef.py but it generates slightly different offsets for different device certs even if I use the same signer certs which means I'd need to compile in a different one for each device.

I saw that the utility calls cert2certdef.py itself but I'm not sure if it saves it to the device.

How should I do this correctly? Is there a certain nice way or do I need to write the cert_def manually into some custom storage?

Thanks for your help in advance!
