Hello Nvidia,
I am developing my own carrier board for TX1.
The question is about USB 2.0 interfacing.
I am using only USB0(microusb) pins - B39, B40. And the external 5v power(about 5.2 - 5.1 v.).
When the USB 2.0 stick plugged in usb connector and Jetson TX1 powered with 12v, the stick’s LED is blinking.
When the Jetson power button was pushed and it starts loading, then the USB stick’s LED is off and i do not see any usb flash drives in the system(lsusb, fdisk -l).
I have made connection TX1 B37 pin to 1-st USB pin(5v), but result the same.
All devices (hubs, flash drives) don’t work. When USB device connected to TX1 and 12v connected too, then usb devices led is on. After TX1 power on button pushed, usb devices led is off.
Also i can’t see any USB_DET B37 pin connection in P2597_B02_Concept_schematics.pdf in USB 2.0 section.
What’s your connection of ID pin of USB connector? It should be to USB0_OTG_ID (pin A36). For host and device mode setting, please refer to below topics:
