How to : Pandaboard ES (REV A/B2/B3) Driver/Kernel Debugging ?

Softy342

Hi,

Before trying I have been reading about the Linux driver/kernel debugging on Pandaboard with appropriate tools - software and Hardware.

My Objective is to debug the I/O ( USB,UART, I2C, SPI) driver - Built-in or Loadable ,running on the Pandaboard (REV B2 - Hope the same for all the revisions after A) on a Linux Platform(Ubuntu 12.04 LTS).I don't have any H/w tool currently.I want to :

1.Step in and Out of the driver functions using a GUI Debugger (where I can list/enable/disable/delete Break Points)

2.Collect the traces/Dumps while running the code.

I have collated my finding as below :

Software Tools :

(1) CCSv4 is suitable for Linux debugging.

(2) If I dont have CCSv4 and even a h/w tool I can use kgdb on serial Port.Correct?

(3) Crash Debug tool(But it is only for vmlinux and vmcore)

Hardware Tools :

(1) JTAG/JLINK(How many Pins?-13 PIN? .Any connector for the normal JTAG

(2) JTAG using Bus Blaster? Any limitations/Dependency of this.

(3) Lauterbach (too costly), Any other in-expensive Debugger

PLease let me know how to kick start of the debugging setup with some example/Tutorial

Thanks in advance,Really looking forward to get this started !

Hello Raul P,

The answers of your questions are:

Software Tools:

(1) CCSv4 is suitable for Linux debugging. - Yes, CCS comprises a suite of tools used to develop and debug embedded applications.

(2) If I dont have CCSv4 and even a h/w tool I can use kgdb on serial Port.Correct? - Yes, you can use kgdb.

(3) Crash Debug tool (But it is only for vmlinux and vmcore) - vmlinux vmlinux is a statically linked executable file file that contains the Linux kernel. For vmcore see the link - http://manpages.ubuntu.com/manpages/oneiric/man8/kdump-config.8.html

Use the following links for training: -

1. http://processors.wiki.ti.com/index.php/Oprofile_User%27s_Guide

2. http://processors.wiki.ti.com/index.php/Debugging_on_DaVinci_using_kgdb

3. Refer to TI's Linux forum for SW questions - http://e2e.ti.com/support/embedded/linux/f/354.aspx

Hardware tools:

(1) JTAG/JLINK (How many Pins?-13 PIN? - JTAG connector has 14 Pins. This is standard configuration one of them can be unused. See the link for OMAP4 debug and trace tools - http://processors.wiki.ti.com/index.php/OMAP4_Debug_and_Trace_Tools

(2) JTAG using Bus Blaster? Any limitations/Dependency of this. - In the link above is the official JTAG for OMAP devices.

(3) Lauterbach (too costly), Any other in-expensive Debugger. Yes, this is costly tool, however it is the most powerful tool for development (debugging and etc.)

PLease let me know how to kick start of the debugging setup with some example/Tutorial - The tutorials you can find information in the link http://processors.wiki.ti.com/index.php/Category:CCS_Training
