I have a 2 month old RFSoC 4x2 board I got from RealDigital. I loaded a new version of 3.0.1 from the pynq web site and booted up the board, with a micro USB cable plugged into the PROG UART input and a USB 3 cable plugged into the USB 3 input. Both are plugged into my Dell Laptop running windows 11.
I booted it up and all seems ok. The LCD tells me that the IP address is 192.168.3.1, which is fine, and I believe that says that the ARM chip successfully negotiated an IP address with the laptop. I ran putty and configured the correct COM port, 115200 baud rate. When I booted the board, I got all the usual linux bootup messages. And I can issue linux commands. Looks good. However, the stout on the USB micro connection through putty keeps telling me this:
[ 678.424311] usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
Over and over again, it never stops.
I did a shutdown through linux and here were the last lines, maybe this is a clue:
[ 874.428110] [2462]: Failed to remount ‘/’ read-only: Device or resource busy
[ 874.440354] systemd-shutdown[1]: Failed to finalize file systems, ignoring.
[ 878.180315] usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
[ 882.256312] usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
[ 882.263291] unregister bridge display which is owned by other component
[ 882.269946] unregister bridge display which is owned by other component
[ 882.277637] reboot: Power down
Also, of course I asked ChatGpt and it ran me through a bunch of tests. Here is what it came up with:
## Bottom line
*** Your hardware is fine (HS path enumerates devices; A001 hub is a supported part).**
*** The SS side isn’t coming up because the current image likely isn’t toggling the hub’s SS reset/power.**
*** You can either suppress it (HS-only overlay) or fix it (small DT overlay to power/de-reset the SS hub).**
Anyone have any good ideas? Could this be a hardware problem? I know that the USB chip is USB5742 A001. Any help would be very much appreciated.
