Hello,
I have a custom board based on the Beaglebone Black, I'm trying to get the board to boot from USB, with nothing programmed on or SD card. I'm expecting to get the AM335 RNDIS to initiate as an Ethernet device. On our board (compared to the Beaglebone Black), we're using USB0 with the OTG circuitry (instead of USB1) and forcing USB0 into device mode. The board is detected by the Linux PC, however, It will not enumerate. The following is the dmesg I was able to get (running Ubuntu 12.04): [424595.900132] usb 5-2: new full-speed USB device number 4 using uhci_hcd [424596.075024] usb 5-2: unable to read config index 0 descriptor/all [424596.075032] usb 5-2: can't read configurations, error -71 [424596.188220] usb 5-2: new full-speed USB device number 5 using uhci_hcd [424596.251145] usb 5-2: unable to read config index 0 descriptor/all [424596.251158] usb 5-2: can't read configurations, error -71 [424596.364184] usb 5-2: new full-speed USB device number 6 using uhci_hcd [424596.422150] usb 5-2: unable to read config index 0 descriptor/all [424596.422164] usb 5-2: can't read configurations, error -71 [424596.423023] hub 5-0:1.0: unable to enumerate USB device on port 2 The board hardware has been modified slightly from the Beaglebone Black. First, we are using a type A usb connector, second, USB0 is now connected to the (USB1) OTG hardware, with USB0_ID pin floating (no access to USB1). Are there any other modifications to hardware required to get this working?
