HAB events with signed u-boot (wrong keys)

Hi,

We are working on a custom u-boot for Sabre i.MX6QP using the HAB to authenticate the u-boot image. We generated the keys chain and corresponding hash. We fused the hash to the board (but didn't close the device). We tried to load a not signed image first, and the verification failed as expected. Then, we tried a signed u-boot, and there were no HAB events generated, which is fine.

Then we tried to use a different keys (all chain was generated again from scratch) for the u-boot signing but no HAB events were generated during the verification (always calling hab_status()). Do we need to close the device to see any error event?

Thank you,

Leonardo
