Dear Team,
We are using two GPO signals(GPIO Module) connected to pin C13 (gpio3_19) and pin C12 (gpio3_17) of AM3359 Sitara Processor , Processor GPIO is configured as output.
The GPO signals are pulled up with 4.7K ohms by 3.3V-1,but processor is powered by separete 3.3V-2. 3.3V-2 supply is separete from 3.3V-1.
There is a chance of powering 3.3V-1 power to Pull up resistor first than the 3.3V-2. Will there be any issue while connecting the GPO signals to Processor module when 3.3V-1 is powered first.
Regards,
