Therefore, change the status of the timer nodes to "reserved" to avoid any clash. Usage is described as below: +===================+=============+ | Remoteproc node | Timer Node | +===================+=============+ | main_r5fss0_core0 | main_timer2 | +-------------------+-------------+ | main_r5fss0_core1 | main_timer3 | +-------------------+-------------+ | main_r5fss1_core0 | main_timer4 | +-------------------+-------------+ | main_r5fss1_core1 | main_timer5 | +-------------------+-------------+ | c71_0 | main_timer0 | +-------------------+-------------+ | c71_1 | main_timer1 | +-------------------+-------------+ This change is already incorporated for timer nodes in the MCU voltage domain.
