KGDB - does not work with TI's SDK

Hi Ran,

You can search internet and you would get lot of patches for this and try to patch into your kernel.

Hi Titus,

I searched the internet....
I did not find patch for 2.6.37. Do you know maybe where I can find it ?

I also don't understand why the git in SDK does not contain ethernet support if the explanation in the link
http://processors.wiki.ti.com/index.php/Debugging_on_DaVinci_using_kgdb  used the ethernet for the debugging.

Anyway, If it is not founded, I thought of using the existing kgdb from SDK, which supports serial.
But When trying to do I get the following error:

root@dm814x:~# echo ttyS0 > /sys/module/kgdboc/parameters/kgdboc
kgdb: Registered I/O driver kgdboc.

root@dm814x:~# echo g > /proc/sysrq-trigger
SysRq : DEBUG
Entering KGDB
Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c4368000

Is there any way I can use TI's SDK with kgdb  (serial/ethernet any option that works will be OK) ? It is most essential.

Thanks for any idea,

Ran

Hi Titus,

Can you work successfuly with kgdb (serial or ethernet does not matter) with TI's 2.6.37 ?

Thanks,

Ran

Hi Ran,

Have you tried anytime with "gdbserver  ?

Please refer the following TI wiki.
