TMS320C6678: Testing GPIOS on TMDSEVM6678L

Dear all,

I must be too clumsy, but I'm not succeeding and maybe you can help me. I think is a very simple question but for the moment  I am not able go on.

I am trying to test GPIOs on TMDSEVM6678L using my  own program. I would like to switch on/off GPIO15, which is on pin 80 of the connector TEST_PH1. With a polimeter in that pin,  I am able to see if this GPIO switch.

The program I am using is the same as the "UART_BasicExample_C6678_C66xExampleProject" with minor modifications, basically I have added the lines to toggle GPIO15 and the includes I think are needed.

This is the full program:

Next picture are the includes:

When building I get:

error #10234-D: unresolved symbols remain

I have tried many things but without succeed.

Doy you have an idea what I miss?

Are the lines to switch on/off the GPIO15 correct? Do I need anything else?

If you need any further information please let me know.

Thanks in advance,

Joaquin.
