TMS320C6745: TMS320C6745 GEL file related issue/ GPIO not working in TMS320C6745

Part Number: TMS320C6745
Other Parts Discussed in Thread: TMS320C6747

I have apiece of code for enabling and writing GPIO and blink LED. This code is working fine in OMAPL137 board with TMS320C6747 core. When same is tried in TMS320C6745 processor (One board I ve designed), it is not working. It is not writing to the memory assigned for GPIO.I ve used the default GEL file for OMAPL137 & TMS320C6747. But not working in both. I dont have GEL file for 6745. . But I am able to connect the 6745 board (which I ve designed) to CCS and able to debug and put preak points. So only GPIO related stuff is not working.Please help me

This is a bare metal code, right? You're not using Processor SDK RTOS?
If yes, then try downloading the Processor SDK RTOS and see the gpio examples there and adapt them to your application.

Hello Vinoj,

As Yordan mentioned, I recommend verifying your HW by running the GPIO example in Processor SDK first:

www.ti.com/.../PROCESSOR-SDK-C6747

What is the GEL output when you use the C6747 GEL on the C6745? The devices are very similar so the GEL should work, but there are fewer peripherals on the C6745 so you may need to remove those from the GEL file first.

Yordan,

I m not using RTOS. It is a bare mettle code.

I ve tried the same code in OMAPL137 and it is working perfectly.

Can you suggest me, which are the sections in the GEL file of 6747 to be removed before using it for 6745
