Hi
I have panda board (omap4430 <http://www.ti.com/product/omap4430>) , I am
trying to debug omap4430 <http://www.ti.com/product/omap4430> board using
trace32 [Lauterbach].
Can you please provide procedure to debug u-boot code kernel code.
I had installed trace32 and PC is identifying trace32 through serial cable.
I wants to know steps to follow for debugging the boot code and kernel code.
I have gone through net, I came to know , need CMM scripts [board specfic
CMM scripts]
can you please provide the same and further steps to debug the code.
Thank you in advance.
Regards
Satish.G
