3.2 Remote USB operation
You can control the Motherboard Configuration Controller (MCC) through the Debug USB port.
To enable remote USB operation, you must set the USB_REMOTE parameter in the config.txt file to:
• TRUE to enable the remote USB feature.
• FALSE to disable the feature.
You initiate a command by putting a file into the USBMSD root directory through the USB port. You can
reboot the system, reset the system, or shut down the system by using one of the following filenames:
• reboot.txt.
• reset.txt.
• shutdown.txt.
The MCC detects the presence of the files, performs the requested command, and deletes the file.
Note
The contents of the files have no effect. They can be empty files.
