Hi all,
i work with ezdsp tms320lf2407a.
while compiling my c program in CCS ....i got the following error:
undefined first referenced

--------- ----------------

>> error: symbol referencing errors - example_c.out not build

Build Complete,

Any help on this error will be appreciated.

The problem is there might have been some minor mistakes in the interrut vector table(IVECT.C).For example in your interrupt vector table if you have
enabled an interrupt like TIMER1UISR() and called in the source as TIMERUISR() you will get an error of the following type.So please check the interrupt vector table. Start a New Thread
