* 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:
<pre>
diff --git a/arch/arm/mach-omap2/board-tuna.c b/arch/arm/mach-omap2/board-tuna.c
index a022a43..7098227 100644

}
</pre>
* 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
