BL instruction with no sense for me

Stefan Bauer

Hi,

I'm working with the AT91SAM9260 controller - but I think it's a software problem.

I try to go to another c-function located at 0x200003A8 but the assembler code is very different

//c-code: status = function(pEmac);
//both variables are defind as well as the function

0x2000052C E1800006 ORR   R0, R0, R6
0x20000530 EBDFFF9C BL    0x1F8003A8
-> there is the error

the whole programm is running in the sdram. How could I get the information for this BL jump in the program?

best regards
Stefan

    A few questions:
    Does anything work at all? Any part of code?
    Does firmware upload work correctly?
    Does external memory work correctly?
    Is memory layout for linker configured correctly?
    Could you post longer snippets of disassembled code? It's difficult to match C and assembly code in the samples you posted.
