Hi,
I'm trying to understand where "fault_s" signal in heroncell_dccm module holds unknown value at the power-up.
My system consists of 2 CPUs which are R5 and A65. First of all the R5 wake up then A65..
Problem is that R5's module heroncell_dccm's fault_s signal hold unknown value.
After SOC_FSM_WAIT_POR_STABLE state, fault_s is asserted with clock running.
I'm confused that I can ignore this unknown value in SOC_FSM_WAIT_POR_STABLE state or not. Because this unknown value propagated to dccmout, dccmout2 of R5 at power-up.
It makes error message "Fault Signal Level Error" in SAFETY function during SOC_FSM_WAIT_POR_STABLE state .
