It is possible to control the MPS2+ Motherboard Configuration Controller (MCC) via the USB2.0 Configuration port. This functionality is described in the MPS2+ Technical Reference Manual (TRM) section 3.2 "Remote USB Operation".
The reboot.txt method does not work correctly with the firmware version delivered with MPS2+.
A new version of firmware (mbb_v300.ebf) is now available that fixes this issue. A download of the new firmware is provided below.
The fix also requires a change to the contents of reboot, reset and shutdown .txt files.It is necessary to make the following changes: A string must now be written at the start of the text file. reboot.txt must contain - "hsyxhj" reset.txt must contain - "jkmcgx" shutdown.txt must contain - "bmqjfe" Examples of these files are also provided below. The rest of the method for performing the reboot, reset and shutdown action has not changed.
