Note: This was originally posted on 4th March 2009 at http://forums.arm.com

Hi All,

          My application is not running in ARM Cortex A8. But same application is working in ARM9e. I have compiled using --cpu=cortex-a8 or --cpu = 7-a. Is their any specific options i have to give.

          Currently i am using RVDS4.0. And also i have tried in Code Sourcery(ARM GCC). Their also i am facing the same problem.

          Can any one please help me solve this issue.

Best Regards,
Ranjith Kumar

Is the memory map you are giving the linker correct?

Are you using any CP15 operations - such as MMU and cache maintenance? These have probably changed.

Can you connect a debugger and tell us actually what is going wrong? Diagnosing "stuck in a loop" is impossible because it could be anything really... Information such as whether it is a data abort / prefetch abort / what instruction is faulting would be useful - etc...
