2014.4 Petalinux - Linux Kernel Clears Hardware Breakpoints


The PetaLinux kernel periodically clears hardware breakpoint registers. 

This breaks JTAG debugging. 

Breakpoints misbehave and do not get triggered.


The patch attached to the AR should resolve the issue.

Please apply the patch to the Petalinux 2014.4 Kernel.

This issue is already resolved in the Master branch of the Xilinx Linux kernel.

To apply patches to the default kernel, please refer to (Xilinx Answer 55978)
