Hi, I have a NUCLEO-U3C5ZI-Q board, and I'm trying to follow the DUA_USER attestation process.
I noticed that the existing Root CA certificates like here https://github.com/STMicroelectronics/STM32CubeU3/blob/main/Utilities/Certificates/ do not verify a U3C5 leaf.
Is there another source where I could find such root certificates, and/or is there a plan to add the DUA root CA for U3C5 to STM32CubeU3?
Also X-CUBE-RSSe doesn't seem to ship with a U3B5_U3C5 key-wrap binary.
