Tool/software:
Hello,
We are in the middle of bringing up a custom board using an AM68A. We are using MAIN_UART3 for our serial console. We followed the instructions in UART Log Debug System on Jacinto 7 SoC to change the serial console from the default of MAIN_UART8 to MAIN_UART3, including rebuilding ATF and OP-TEE. We are getting the serial output on MAIN_UART3 as expected, but run into an issue on the A72 when we reach OP-TEE. Please refer to the serial output below:

I was able to rebuild ATF without the SPD=opteed argument when running make. This allowed me to workaround the OP-TEE issue and can verify that I can begin to boot Linux.
From the logs I included, it looks like the A72 is unable to communicate with the R5 sciserver, but I'm not sure. I'm using version 10.00.00.08 of the Linux SDK and I'm building u-boot using the top level makefile. Can someone guide me on what I can do to resolve this OP-TEE issue?
Thanks!
