Hello Akshay.
Trying to port OP-TEE to Atmel SAMA5D2 board (ATSAMA5D2-XULT) - single core ARM A5. I do not see any serial messages after MMU gets enabled (bl cpu_mmu_enable), neither does op-tee go onto load linux kernel.
Just to be sure: does CFG_TEE_LOAD_ADDR corresponds to the real address where u-boot loads optee image? Also, I'm bothered by thread id (0x5f5ed35e in your case). It should be 0x0.
