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, main_timer2 | +-------------------+--------------------------+ | main_r5fss0_core1 | main_timer1 | +-------------------+--------------------------+ This change is already incorporated for timer nodes in the MCU voltage domain.
