hi,
when i debug an empty project created follow the cw wizard,it works ok(flash mode),
but when i change the code start address
internal_flash: org = 0x00020000, len = 0x00060000
in -flash.clf. it does not work,can you tell me why? it is an empty project, i do not
add any user code.

for example i change org = 0x00020000 to another address org = 0x00100000, it can not work. it always reset. and can you tell me why? can you tell me something about how to change my code start address?

the tools i use are P&E powerpc nexus debugger,codewarrior for mpc55xx V2.2 and Axiom MPC5554evb board .

thanks, regards

Hi,

Just an idea : did you check the option Settings->Linker->EPPC Linker->Generate ROM Image? There are two text box there : RAM Buffer Address and ROM Image Address.

I had problem when I activated that. It forced me to have a ROM application. I also suppose that this address must match that of your lcf.
