Firmware Updates
Firmware Updates
Firmware updates in the Kiwi-8P are
more involved than other
Kiwitechnics Upgrades due to the
fact that there are two cpus and
each need their own firmware files.
Because all midi must enter the main
cpu and updates for the voice board
cpu need to be passed between the
boards.
It is most important therefore that
files are loaded in the correct order.
First must be the CPU Boot loader,
second is CPU Program, third is VB
Boot loader and last is VB Program.
The CPU & VB Program files are
large and not all midi interfaces can
handle these. There are many cheap
USB to Midi interfaces and these will
more than likely have problems.
Symptoms will be the file freezing
midway and the update not working.
Note – If all the LEDs turn on then
there was an error during the update
and you should repeat the update.
When a firmware update file is playing
into the Kiwi-8P the display will
change to show the file being loaded
and the 6 LEDS will show progress by
rotating. If the display does not
change and the lights do not show
then the file is not being transmitted to
the Kiwi-8P correctly and you should
check your midi setup.
To start the firmware upload press
and hold the MIDI PANIC button as
you power on the Kiwi-8P. The display
will show 'WAITING 4 UPDATE' and
you then play in the first file. Repeat
this for each of the 4 files.
Note – During VB update all activity in
the voice board is stopped. This can
cause random noise to sound out the
output as the MUX is no longer being
updated and this can get quite loud. It
is recommended to turn down the
volume during this process.
