Hello,
I have a board with MPC852T, SDRAM and FLASH. I have been successful to get the console up and debug the FLASH and SDRAM connections. Now the SDRAM passes all the memory tests in SLOW mode also. The current problem I am facing is that relocate_code is being called from the lib_ppc/board.c and after that there a no messages. I want to debug the relocate code which is written in assembly language. Please help. I want to write something on portA data register to monitor the progress, in the assembly code. I am looking for a small snippet of assembly code that can write to portA register, to be put in the assembly code of the relocate_code. If someone could guide me to access the IMMR and the portA registers using the assembly language, it will be very helpful
