Hello community, using T1042RDB, I am trying to debug my own u-boot ( sdk compiled ) with Code warrior to learn how it works. 


I have a custom board and I want to debug my customized u-boot on it later.


According to, 5.2.2.  Stage 1 – Debug NOR for AS0, after I wrote "setpicloadaddr 0xfff80000" command to shell, I think I had some kind of error. "No source available for "0x00000000FFFFFFFFFC (0x00000000FFFFFFFFFC)0 " and "?" on the given memory locations in Disassembly screen. 


What is the meaning of "?" ? How can resolve this? What is the procedure to debug U-boot with T1042 processor ? I also tried "setpicloadaddr 0xe800000" which is nor flash adress of t1042 rdb. Nothing changed.
