jetson tx2 usb problem

hi,
VDD_5V0_IO_SYS is generated by carrier module, I am generating this voltage when CARR_PWR is set.

  1. what are the other jetson module condition to supply EN0 and EN1? Please consider that the LAN is working fine.
  2. could I have an additional reference doc to check?
    In the DG is stated that after power-on ( please consider I am using automatic power-on, ACOK to ground) these two signal should be set.

Please let me know any suggestions

thank you

Does same module and same sw work on carrier board of dev kit? Did you check the pin setting in Pinmux Sheet to set these two pins to SFIO0 function?

HI,
thank you for your time,
I checked the file you referenced, looking at it seems that is right to have the 2 pins (I mean EN) low, I am reading the column AC, named pin state, where they are set 0.

but the same module installed into the evaluation module is working fine. May be an HW config that I do not know.
Please spend some other of your time ti help me

thank you
maurizio

N.B. really I do not know the meaning of SFIO0 function

SFIO0 is column H in sheet, it tells you the pin function can be set. You should set them to USB_VBUS_EN0 and USB_VBUS_EN1 in column AQ and press “generate DT file” in sheet to generate dts and load in sw.
