Could anyone give me an example of setting a pin as GPO and set it high using pspdrivers_02_20_01_00, i am working on DM8148.

The 2.20.01.00 does not have the support for GPIO driver.

yes, i know. i mean through registers directly. When i try to access any register in the GPIO module in DM8148 the application crashes.

What is the base address of the GP1 module in DM8148.

Mohamed,

Please refer the section 2.12 (Memory Map) of the http://focus.ti.com/lit/ds/symlink/tms320dm8148.pdf document to get the base address of all the peripheral in the DM8148. You will find the GPIO base address in this section itself.
