During a context switch (use of SVC instruction), I encounter an error stating "no source for g_pfnVectors() at 0x0"
I have used the default startup code given by the embedded artists for LPC17xx.
Is the cause for error,  reset vector not accessible??

The optimizations and debug level has been set to 0.

I have attached the disassembly of the code.
any help would be greatly appreciated.
