I don't know how to write dspside program on omap L137 in linux?

I have the test example codes of omapL137 ,I run the examples in CCS

 environment,and they are all OK.

Now, I want to use these examples in linux environment, can I use these codes directly?

I did a test,I add some codes to main() Function of Loop example in DSP/BIOS LINK,

I set GPIO to low level,it works. The codes are

PINMUX11 &= 0xFF0FFFFF;PINMUX11 |=  0x00800000;GPIO_DIR23 = 0; GPIO_OUT_DATA23=0;

Is my way right to control Peripherals or Internal module?By the way ,which timer can be accessed by DSP?

I need some opinions or documents! Thank you very much!
