I have below questions related to System Timer of TC3777. Can you please help clarify.
1. In our application we are planning to use system timer of TC3777 as the source for Real-Time OS.
Plan is to configure System timer ISR and use ISR to increment OS-counters which activates the Task.
Is there any concern with using system timer to run OS ? or is it better to use the GTM ? I am assuming System timer is designed for running OS tasks. Any thoughts or comments on this will be helpful.
2. Are there any hardware safety mechanisms implemented on this timer to check plausibility etc for the timer.

Every operating system I've seen uses the STM, but you certainly could use the GTM instead.
There aren't any hardware safety mechanisms that cover the STM or the GTM.
