Hi,

Although many debugging tools claim that they could support ARM architecture such as KDUMP, LKDC Crash Uitlity,etc, they are unstable. I just can suggest to try: Kernel/KernelDebuggingTricks - Ubuntu Wiki  in case of i.mx6 debug kernel.

  Or you should try to Build Linux Kernel and make sure that the feature kexec and debug info are enable.
·         Boot options  —> 
·         [*] Kexec system call (EXPERIMENTAL)
Kernel hacking  —>
·         [*] Compile the kernel with debug info

Regards
