So I have been working on getting secure boot working with a p4080 and U-Boot, and right now I seem to be having issues with the validation of my image.  The sec_mon register is in the check state, which according to the trouble shooting means that the

Hash of the public key used to sign the ESBC u-boot doesn't match with the value in SRK Hash Fuse Or Signature verification of the image failed. I followed the steps listed in the 1.9 SDK documentation when creating the CSF and signing the image with my generated keys, so I am not sure what the next step is to try with verification / troubleshooting.  Is there a way to see what hash it is generating when it compares the two hashes? Or is it possible I am still missing a step or file?
