I want to use the USB-OTG for programming the SOM, and I found that USB0 interface is also shared with the PMIC-AXP803, Default communication interface between PMIC and A64 SoC is I2C/RSB interface.
1. Why is this USB0 port is connected to PMIC?
2. Will there be any problem while programming SOM on USB0 lines since the port is shared with PMIC?
3. Where do I connect the USB_OTG's 5V supply line? Will there be any enabling pin to enable USB0 port to program SOM?
Awaiting a reply.
1. For charger detection. This function doesn't apply to PINE A64.
2. Should be OK.
3. You can connect USB_OTG's 5V supply line to program SOM.
