After powered up ,the IMX8Q's BB50 (SCU_WDOG_OUT) ouput like that ,cann't detect usb ,and I tie this pin to WDI belonged to pmic ,and this waveform make PMIC reset at 3,243Hz,can anyone know how to solve this problem ,thx a lot
In default SCFW, it had already used internel watchdog to make sure SCFW is always running, if SCFW is built as no debug version (M=0 D=0), all SCFW halt will cause SOC reset. And if hardware had connected the SCU_WDOG_OUT pin from iMX8QXP to PMIC's WDI pin, then during SOC reset, the PMIC will also do hard reset to make a POR reboot for the whole system.”
