QRP Labs QMX User Manual

The QMX firmware is 256-bit AES encrypted and this means:
• The encrypted QMX firmware file will only work on a QRP Labs QMX board, it cannot be
installed on any other board, even one containing the same processor.
• No other firmware file will work on the QRP Labs QMX board except an official QRP Labs
encrypted QMX firmware file.
The procedure will vary slightly for different Operating systems but in all cases is just a simple
matter of copying the new firmware file to the emulated QMX QFU USB Flash drive.
The above firmware update procedure works on ANY modern OS because the QFU
bootloader emulates a USB Flash memory stick with the USB Mass Storage Device (MSD)
class, for which drivers are already present.
The QFU bootloader implements a USB device stack (Mass Storage Device class), emulated
FAT16 file system, Flash erase/write, and 256-AES encryption.
