We are having a little issues with the USB on the go port. We are trying to use it in peripheral mode.
Our USB cable is a A to mini-B and pins 4&5 are not shorted. We are connecting this cable to a PC.
USB0_ID is always low regardless of cable presence.
The AM1808 SPRS653C 2.7.17 says that USB0_ID is an analog input w/o a pullup.
It doesn't say that it needs an external pullup either.
The AM1808 TRM SPRUH82A 34.2.2, 34.2.7 says to leave it floating for peripheral ops.
It doesn't say what voltage it would be when floating.
What voltage with USB0_ID be when the pin is floating? We can't seem to get it to show up as a peripheral.
Thanks,
Tim
