SK-TDA4VM: Unable to modify the interrupt period of the clock

Part Number: SK-TDA4VM

Tool/software:

Hy Ti developers,

I am working with a custom SK-TDA4VM–like board that is functionally identical to the TI reference design, using Processor SDK RTOS (ti-processor-sdk-rtos-j721e-evm-09_02_00_05).

My objective is to configure the MCU GPT timers on the MCU R5F core for different tasks. Currently, I am using MCU_TIMER4, with the clock source set to wkup_rcosc_12p5m at 12.5 MHz.

The issue: when I modify the TLDR value, the interrupt interval does not change.

The static register values are as follows:

  • TIDR: 0x50003900

  • TLDR: 0x0000000F

  • TIOCP: 0x00000004

  • TMAR: 0x00000000

  • TCLR: 0x00000043

Any advice? 
Regards
