Hello Everyone,

 

I have been running into some problems when trying to debug a kernel module using codewarrior IDE for Power and a Giga bit probe.

Kernel debugging works perfectly fine with both SW and HW breakpoints hitting. However when I try to debug a kernel module then none of the software breakpoints placed inside the kernel module gets hit, though I am able to get HW bp's hit in the KMod which points to something that the module actually tries to access the addresses on which the breakpoints are being placed.

 

I have built my kernel with debug information and includes CodeWarrior Debug Support from the kernel menuconfig.

 

Is there any thing else which I am missing ?

 

Thanks,

Saqlain.
