I'm having a hard time building a kernel with kdbg support. In ltib i was able to configure the kernel and everything seemed to build. I'm using a nitrogen6x board though, I'm not sure how much stuff this will break.
Starting up with uboot I added kgdb args
setenv bootargs kgdboc=ttymxc0,115200 kgdbwait ip=dhcp
it doesn't stop, I aslo don't believe its loading the correct config to build, my kernel with debugging symbols is about the same size as my kernel without....
I tried to build directly with the sources, but when I do that, after configuring the kernel, it automatically restarts the config process... from the beginning without a menu.
My second problem is I have two serial ports, and my device is deciding to use both during startup, At some point it switches console output to the second serial port.
