We added support for certificate key usage/purpose in 1.3. Is this a regression compared to 1.2? > I am running rauc info [name of the bundle].raucb on the device.

Could you upload the output of openssl x509 -in <foo.pem> -text for all certificates somewhere so we can check that? This looks similar to https://github.com/rauc/rauc/issues/568, but so far we haven't found the underlying cause with the certificates in that issue yet. > I don't really know how to get past this issue.

The variables look fine. Regards, Jan _______________________________________________ RAUC mailing list
