Hi all,
I am trying to port u-boot on a board based on MPC8560. I am using TRACE32 as a simulator ( and ICD ). In case of my board, CCSRBAR = 0xA000_0000 and there is no memory attached at 0XFF70_0000 ( i.e at default CCSRBAR address ). During simulation I observed that in file "cpu/mpc85xx/start.S" ( line - 276 onwards ), it tries to modify old CCSRBAR value the with new one. But as there is no memory at default CCSRBAR address (0xFF70_0000) , will it work in real senario ? ( i.e when i will run this code on the actual card ). Am I missing something? Do i need to change the value of CFG_CCSRBAR_DEFAULT to such a location on my board where some memory exists. During simulation, while stepping through U-Boot's code (e.g in file cpu/mpc85xx/start.S ), values of the registers like CCSRBAR, LAWs etc are not changing. What should I do?
Do help me...its pretty urgent. Thanks in advance
