Running "dmesg" via telnet connection resulted in a hang of the USB driver (likely), but since I have serial connection to the board, I was able to verify the board itself didn't crash. I can still operate the board via serial console, it's only the USB in peripheral mode ethernet that is hung. > Shawn, marek reported the udc function at mx23 works abnormal, but it works > good at mx28.
