* http://redmine.replicant.us/projects/replicant/wiki/S5PC110Bootloader works as a serial cable.

When you connect the cable you get the FIQ debugger, but what if you want kgdb instead:

* apply that patch:

* remove the FIQ debugger in the kernel configuration.

* change the CMDLINE trough the kernel configuration:

Use:

<pre>CONFIG_CMDLINE="console=ttyO2 androidboot.console=ttyO2 [...]"</pre>

Instead of:

<pre>CONFIG_CMDLINE="console=ttyFIQ0 androidboot.console=ttyFIQ0 [...]"</pre>

Verify that you get the kernel messages.

Then change the cmdline for kgdb
