2008-10-05 06:31:36     Tools for kernel crash (Hard lock up) analysis on Blackfin

Message: 63117   

 

I am having a completely hard locked up kernel on Blackfin 533 2008R1.5. I am using a jtag

 

and gdbproxy/gdbserver to dump memory out and check the kernel stack.

 

I know there are a few tools around for analysis like LKCD but there is no  support for BF.

 

Do you know any other tools that can use on BF for mem dump analysis?

 

Any other ideas of how to trace this hard-lock up?

 

 

 

Best

LKCD and such tools are just replacements for having gdb and jtag.  they do post-crash analysis.  being able to hook up jtag and gdb is better as that gives you live debugging.

 

you can try using sysrq to dump active states:
