Lpc2000

Hi All,

 

I am using the LPC2210 with uC-OSII.  I am in the process of writing exception handling routines.  Does anyone

know if there is a 'best know method' to do this?  I basically want to dump as much relevant info as possible about

the processor state before the exception.  I am finding that my solution is not very elegant and I don't want

to overlook a simpler method.

 

What I have now, in the Data Abort case:

 

-          I get an exception and jump to the corresponding vector

-          I switch to System mode and push r0-r15 onto the System stack

-          I put the System SP into r0

-          I switch back to the Abort mode and preserve SP_abt and LR_abt in r1,r2 and then put r0 into SP - I then put r1 and r2 on the stack (System stack). 

-          I switch back to System mode and then call a C routine which prints all of this out

 

 

Does anybody know of a better way?  Any tips?

 

Thanks!
