OOTLOADER

48.

The new USB functionality now supports software updates in the field via USB flash drives.
To allow this to occur each ZMCU contains two software components namely the
bootloader and the firmware. To run the bootloader it is necessary to fit the jumper labelled
ENG_LK and restart the machine. Once the machine starts up the display will show:

B

OOTING

…

(001)

49.

The lower line of the display is the Bootloader version number and is not to be confused
with the actual firmware version number that can be loaded onto the control board to run
the machine.

50.

All firmware must be stored in “.\COFFETEK\ZMCU\FIRMWARE” on the USB flash drive.

On an operational machine any USB activity which saves data to the flash drive will create
this directory automatically. It is recommended to keep this directory small to avoid
erroneous firmware being loaded onto the ZMCU.

51.

The machine will then search for attached USB devices. If a device is not found the display
will show,

PLEASE INSERT
USB DEVICE

52.

If a USB flash drive is attached the screen will briefly say

DEVICE PRESENT

53.

The bootloader will then scan the USB flash drive to see if any firmware updates are
available in the “.\COFFETEK\ZMCU\FIRMWARE” directory. If this directory is not available
the display will say

NO FIRMWARE
DIRECTORY FOUND!

54.

If the directory exists but there are no valid files to upload the display will show,

NO FIRMWARE
FILES FOUND!

55.

If a USB flash drive is inserted that does contain valid files the display will change to,
