Hi Mike,

The core remains the same. There is slight difference in the system
interrupt mapping (and some devices). But that should not cause problem in

The issue i am facing is that the processes execute properly on the virgin
stack. But when the process try to start for their second time slice the
program crashes.

I have made some changes to the code to get to this stage. So my question is
does anyone tried executing the test programs on bfin537Stamp with
interrupts. The reason i ask this question is to identify if the 537Stamp
code was right and i am moving in wrong dorection debuging and changing the
code OR the 537Stamp code is buggy and i have to debug it or look at the 533
