About oMAP-L137 (Dev board) uart example program

Hi,

In uart example code, they have declared 

extern void intcVectorTable (void);

but there is no access to this function.

and when i keep pointer on this function it says "write occurrence of 'vector table'  "

do i need to write that function, if so please give me a suggestion how to write or else if u have sample code for that plz post it

Thanks and Regards

Shankar H

    Hi Shankar H,

    You can find the definitions in the following source file.
    ~ti\quickStartOMAPL1x_rCSL\OMAPL1x\rCSL_examples\evmOMAPL137\DSP_examples\uart\UART_interrupt_loopback_dspL137\src\intvecs.asm

    that ISTP is assigned with intcVectorTable in main.c file.

    Hi shankar hiregadad,

    In "intvecs.asm" the "intcVectorTable" is defined. It is located at "rcsl_examples\evmomapl137\dsp_examples\uart\uart_interrupt_loopback_dspl137\src"
