Hi All,
I am working on Phycore MPC565 board with single step debugger.
In the configuration file of single step the DER register value was
0x73e67c0f. Whenever an exception was generated the debugger used to
display popup messages. To avoid the popup i have reset the bits in
the DER register.
As an example, I have reset the system call exception bit in DER to
check that whenever the exception occurs it branches to the exception
handler (Address 0xC00)
But when I generate a system call exception using a sc instruction and
apply a breakpoint at 0xC00 it does not stop at the breakpoint (This
address is in the internal Flash).
Please let me know why the breakpoint is not activated at 0xC00 and
debug the exception handler code.
Thanks and Regards,
Prashanth
