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_timer12 | +-------------------+--------------+ | main_r5fss0_core1 | main_timer13 | +-------------------+--------------+ | main_r5fss1_core0 | main_timer14 | +-------------------+--------------+ | main_r5fss1_core1 | main_timer15 | +-------------------+--------------+ | c66_0 | main_timer0 | +-------------------+--------------+ | c66_1 | main_timer1 | +-------------------+--------------+ | c71_0 | main_timer2 | +-------------------+--------------+ This change is already incorporated for timer nodes in the MCU voltage domain.
