Beaglebone/CCSV5 Kernel debugging

peg

Hi all,

I've finally succeded in debuging my Kernel with CCSV5 on JTAG USB interface of Beaglebone. (Notice that i had to "clear" project field in my debug configuration either the debugger would never launch with a java null pointer exception ??)

So, i can USB/JTAG debug, But it is very very very slow ...

As an example it last about 30 seconds just to stop the executing kernel et give hand to executed instruction.

Is it because of to much source code, to much symbols, ... ?

Is there any suggestion somewher to optimize Kernel debugging ?

Thanks

Hi Pierre-emmanuel,

May I know what PC, OS and JTAG emulator you are using.

If you do not load vmlinux symbol, how long does it take to stop the executing kernel ?

Also, if you close the disassembly view, does it improve the timing?

Regards,

Raymond

Pierre,

In one of your older posts you mentioned the use of a Virtual machine, therefore please also check the page below:

Unfortunately we experienced severe slowdowns when using XDS100 emulators on Virtual machines, therefore this may be the case.

Rafael
