flyswatter2 and pandaboard

chandrasekhar - February 23, 2012

hi,

I recently brought a Arm jtag debugger from Tincantools and trying to use the same,But as davis anders showed us in an how we can connect the board and then port linux kernel on to the board directly from the jtag really fascinated me.But as i was trying to do the same it was quite difficult to even try and start it.First thing that i wanted to know in this discussion is

1.Is this ARM-Jtag Debugger helpfull for debugging linux platforms ?

2.Do we have a proper manual except from the tincantools wiki for the flyswatter2 ?

3.How well can we use it ?

4.Good instances where this will be helpfull in board bring up or Driver development ?

5.How can i use this Jtag debugger with android on the same ?

I am subjected to discussion on these criteria,I will be very thankfull to all the people who would join this discussion and solve,share the issues and also share the knowledge.

Thanks and Regards,

PullelaChandrasekhar.( PullelaChandrasekhar@gmail.com)

Hello,

Congratulations of your purchase of the Flyswatter2, it's a great little tool. To answer each of your questions:

1. Yes, the Flyswatter2 is very helpful for debugging Linux platforms.

2. There is no "proper" manual. The Flyswatter2 is an open community project, therefore the documentation available is provided by the community in various places. The best place to start is the TCT wiki: http://www.tincantools.com/wiki/Flyswatter2#Pandaboard_-_Linux. You may wish to reference OpenOCD as well, and perhaps adapt the BeagleBoard + OpenOCD reference page for your purposes with the PandaBoard: http://elinux.org/BeagleBoardOpenOCD.

3. The Flyswatter2 is fully supported by OpenOCD as far as I know.

4. Good instances? I'm not sure I understand the question. During board bringup, there are points when you can only access your board via JTAG. However, if you're using this with a PandaBoard, you would likely only require JTAG access for debugging something like a kernel driver.

5. Using the Flyswatter2 with Android on the PandaBoard hasn't been documented very well anywhere, however, it's likely very much the same as debugging any Linux system. See the HOWTOs on the TCT website: http://www.tincantools.com/wiki/Flyswatter2_Pandaboard_How_To

and use Google to find other examples online. I know that there are some Linaro based videos out there that may be useful.

Good luck. Please report your experience.

Unfortunately, your question is not easily answered. The short answer is that a Flyswatter 2 is very useful for debugging Linux issues on a Panadaboard. The long answer to how to do this could fill an entire book.

I suggest reading the TinCanTools wiki page and giving it a shot. Also, google is your friend. In particular, search the Pandaboard mailing list, and panadaboard.org. There's also lots of info on elinux.org.

Good luck.
