TMS320C6748: Why the .gel file cannot works if set 72M/48MHz?

Feng Xu

Part Number: TMS320C6748

Hi,

Attatched is the gel file I used, the only change I made is change the CPU_PLLM from 18 to 2, and DDR_PLLM from 12 to 1.

Which means the CPU is 72MHz and DDR is 48MHz.

When I run the progran in CCS, the break point is not set to the main() and the green start button is not turn on, even after 10 minutes.

But, I have also tried to set 72M/48MHz freq in the Board_Init(), the freq of CPU and DDR is set normally and the program runs well.

My question is, why 72M/48MHz can be set in Board_Init(), while cannot be set in the .gel file?

C6748_72MHz.gel

Hello Frank,

We can no longer support questions about C67x TI_RTOS. I am assigning your thread to another team member to point you to our existing resources.

Hi Nick Saulnier,

Maybe this question is not related to TI_RTOS, it's only related to the C6748 gel file.

Hi Frank,

As Nick mentioned, we can no longer support TI-RTOS or bare-metal SW development on C674x. Sorry about that, but please refer to the following resource:

OMAP-L13x/C674x resources and FAQ

Hi Jianzhong Xu,

Will C674x chips stop production in recent years?

Hi Frank,

No, there is no plan to stop production for OMAP-L13x/C674x.

Hello Frank,

For more information about the product lifecycle, please click on the icon right next to the part number on the product page:
https://www.ti.com/product/TMS320C6748

We can see that it says "active" with a green check mark next to it. Click on the word "active" to go to this page:
https://www.ti.com/support-quality/quality-policies-procedures/product-life-cycle.html

Basically, as long as customers keep buying a part and we can continue to produce it, we WILL continue to produce it. Our ability to keep making a part at our factories is different from our ability to answer questions about creating a design with the part.

Regards,

Nick
