hello,

I am transferring data from ram to EEprom via I2C.

The problem is whenever i call function DELAY_US() from DSP280x_Device.h , I stopped at the interrupt void ILLEGAL_ISR.

Any clue?

Thanks

Sung,

The DELAY_US() function is in a section called RamFuncs which needs to be copied from Flash to RAM before execution time. If you are neglecting to do this you will see wierd behavior such as an ILLEGAL_ISR. Check out the examples in controlSUITE for how to accomplish this.

Regards,

Trey
