We divide the J507 (eSATA and USB 3.1 Type A Connector) into two part: one USB2.0 TYPE A and USB 3.0 TYPE A .
The USB2.0 use USB3_DN/USB3_DP/GPIO22 and can’t work when the same xavier module work fine in offical develop kit. We measure the gpio voltage and check the difference between them:
- The Offcal develop kit : Power up it’s high, then low , then high.
- Our Board: Power up it’s hight, then low always even if enter to the os.
This part is the same as develop kit , so why doesn’t it work
