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_timer0 | +-------------------+-------------+ | c7x_0 | main_timer1 | +-------------------+-------------+ | c7x_1 | main_timer2 | +-------------------+-------------+ This change is already incorporated for timer nodes in the MCU voltage domain.
