Hello,
When we power up the MangoH board, usb enumeration fail messages shows continuously on the debug uart terminal. If we connect MangoH to a Linux PC through the usb cable, i am able to open SSH terminal and it works normally. So how do we stop the error messages on the uart debug terminal? cm info and legato version details are shown below. Also i am facing issues for uploading the boot log, so I just copy the part of error log below.
