Hi there,
After setting up the board followed by the instruction, I connect both UART ports with my computer. For my board one port shows normal world output while other one shows OP-TEE output.
In this case, I'm wondering is there anyway for me to print some information with the code running in the trusted firmware layer?
I see the header stdio.h in the lib folder contains one printf function. However, after calling this function, I don't see any output from either UART port.
Thank you in advance.
Simon
