Hi,

the Am437x have upto 12 timers,If each timer has its own interrupt program, which one has a higher interrupt priority?

How does these hardware interrupts priority correspond to the TI-RTOS tasks priority?

Hi user5371084,

Regarding task priority, you can refer to the below user guide:

software-dl.ti.com/.../index_examples_demos.html

Regarding AM437x timer interrupt priority configuration, you can refer to the AM437x TRM (3.3.1.3 Generalized Interrupt Controller (GIC)) and Cortex-A9 ARM TRM. You should check INTC registers "Interrupt Priority Mask", "Running Priority", etc

You should also refer to the below e2e threads which discus irq priority setup:
