Yes, I've already booted optee via u-boot (proper). It boots fine. > Also in OP-TEE, does the CONSOLE_UART_BASE is configured correctly? Yes, i did. Its UART4_BASE in case of my board and its set. I can confirm this because I booted same optee image via u-boot (proper) and I can see all the logs. If we assume that there is some issue with optee then it should have produced least some minimal logs, but there are no logs at all.
