Hi,
This is my first project with C674X DSP. Could anyone help me with an example to make a simple GPIO write for it without BIOS or PSP lib? My board has memory limit, so I have to write all code for it.
Thanks

Hi Ana,
Please go to the site:
http://support.spectrumdigital.com/boards/evmomapl137/revd/
And get the test code (EVMOMAPL137 Test Code) for C6747. On of the test is the led test that uses GPIO. You can take a look at the test project:
C:\CCStudio_v3.3\boards\evmc6747_v1\dsp\tests\led
and also at the source code of the boars support library (you are going to see in the source code for the library that GPIO are used for the LED test):
C:\CCStudio_v3.3\boards\evmc6747_v1\dsp\lib\bsl\
You can take a look and go from there.
Also, when you follow the GSG and install the software, you can find GPIO example that does not use DSP/BIOS at:
C:\Program Files\Texas Instruments\pspdrivers_01_20_00\packages\ti\pspiom\cslr\evm6747\examples\gpio\
