Hi,
I have built a custom platform based on Cortex-M55 using ARM Fast Model Tools. Everything runs fine except accuracy of systick timer. I have ported zephyr to this platform. The timer seems to be just ticking as fast as it can and I am unable to establish accurate time base for it. In another platform, that I made I used the R82 core with a Memory Mapped Counter Module, I was able to set a property 'use_real_time' after which timer generated accurate time base. However, for M-55 and systick, I am unable to find any such option.
Any help would be greatly appreciated. Thanks.
Best Regards,
Mughees
