Our product use MPC5775K and FS6523. There is a boot failure when the ambient temperature below -25℃。
The initiation process stop at the while loop of FCCU_init() :
FCCU_init() while(FCCU.CTRL.B.OPS != 0x3)
I tried to clear all NCF before config FCCU, but NCF can't be cleared, and SSCM_STATUS.CERS is set and can't be clear by writing '1'.
When ambient temperature goes above -25℃, there is no such issue.
