No Output in U-Boot Console

[tschutte]

I am attempting to secure boot using the p4080 (v2) and U-boot.

when I try to use both the RCW with SB_EN enabled and U-Boot with #define CONFIG_SECBOOT, rebooting the serial console results in the system immediately locking up (I get no output back whatsoever).  I have tried waiting for a while thinking that it needs some time to make it to the prompt, but it never happens.  To be clear, if I build U-Boot with just CONFIG_SECBOOT (no other modifications) and use the RCW with SB_EN bit set, then the system locks up entirely.

status register of sec mon block (location CCSRBAR +0x314014). : Shows as everything is OK

SCRATCHRW2 register : Shows as everything is OK

Sec Mon in Trusted State (0xd) : So everything is OK

Check the entry point field in the ESBC header : Appears to be okay. I have tried moving it around to different suggested locations and that doesn't seem to get anywhere.

Look at the following pages for secure boot. Do you use this command sequence?

Yep those are all the steps that I followed for the p4080 I am working with.
