Hello,

I am having issues when I try to verify a bundle downloaded on the device. I am using rauc 1.3 through the meta-rauc for Yocto.

I am running rauc info [name of the bundle].raucb on the device. The output I get is the following:

rauc-Message: 17:24:54.156: Debug log domains: 'all'
(rauc:528): rauc-DEBUG: 17:24:54.165: input bundle: /var/1/rauc-bundle-raspberrypi3-64.raucb
(rauc:528): rauc-DEBUG: 17:24:54.166: No value for key "max-bundle-download-size" in [system] defined - using default value of 8388608 bytes.
(rauc:528): rauc-DEBUG: 17:24:54.166: No mount prefix provided, using /mnt/rauc/ as default

rauc-Message: 17:24:54.173: Verifying bundle...

signature verification failed: Verify error:unsupported certificate purpose

I don't really know how to get past this issue. I have included in a file the root certificate, intermediate certificate and the certificate that corresponds to they key used to sign the bundle. And I point to that file with path=/etc/rauc/firmware-keyring.pem in the system.conf file.

previous to doing that I was getting:

[...]

signature verification failed: Verify error:unable to get local issuer certificate

With regards to the environment variables this is what I am using:

RAUC_KEY_FILE="/h4-work/certs/rauc/firmware-key.pem"

RAUC_CERT_FILE="/h4-work/certs/rauc/firmware.pem"

RAUC_KEYRING_FILE="firmware-keyring.pem" (which is the file that I am using on the device)

I don't really know how to get past this issue, any points would be highly appreciated.

Cheers,

Diego
