I recently upgraded from LPCXpresso 3.5.x to 4.2.0 and CMSISv2p00 (with an LPC1313).
Now, whenever my code reaches a __WFI() call, the debugger freezes the program as if it hit a breakpoint. The program stack view lists
"Suspended: Signal 'SIGINT' received. Description: Interrupt."
The Breakpoints view in the IDE show no breakpoints (I can still add, use and delete breakpoints as usual).
The Signals view shows SIGINT was triggered.
I get the same problem even with a brand new project generated through the New Project wizard.
1) should WFI cause SIGINT?
2) how to prevent this, or fix it so my program can continue (/not be suspended)?
Thanks.
