Kronos Software Updates

You will need: A FAT-32 formatted USB drive - about $20.00 USD at Walmart.

Updates are located at www.korg.com/kronos.  Select "Support & Downloads" and click the "OS" tab.

Download the update "KRONOS_Update1_5_0.zip" and un-zip the downloaded file.

Copy the following files to the USB drive.

  - mnt (Folder)
  - KRONOS_Update1_5_0.taz.gz
  - install.info
  - posttar.sh
  - pretar.sh

The KRONOS is a realtime Linux-based PC (basically) so you are supplying a new OS along with a new set of application tools (what you see on the KRONOS screen, drivers, etc.)

The "pretar" code does this:

#!/bin/sh
# Kronos installer preparation script
rm -fr /mnt/updaterSource/mnt/lib/modules/2.6.32.11-korg/kernel/sound
kill $(pidof vsftpd)
kill $(pidof avahi-daemon)
kill $(pidof messagebus)
kill $(pidof ifplugd)
sleep 2
kill -9 $(pidof vsftpd)
kill -9 $(pidof avahi-daemon)
kill -9 $(pidof messagebus)
kill -9 $(pidof ifplugd)
sleep 2

Basically this looks like a macro substitution program fills in the pids (process IDs) of the various processes running in RTLinux which are killed off before the install begins (perhaps the things being updated).

The .GZ contains the OS Update.  A quick unpack on Mac OSX fails - probably because its encrypted (no doubt using some info in "install.info" or a standard Korg PGP key of some sort).

In any case, after you've put the USB drive into one of the Kronos USB ports (and disconnect all the other drives and USB cables) you can do the install:

1. Go to the Global P0 – Basic Setup page (Global button - Menu on upper right).

2. Select “Update System Software”.  If it sees the USB drive it will let you know.

3. Press the OK button and a dialog will appear saying: “Are you sure?” Press the OK button.

4. Let the update run and DON'T TOUCH ANYTHING.

5. When the update is complete “Kronos system version 1.5.0 update complete. Please restart the system” will appear on the LCD display.

6. Turn off the Kronos, and then disconnect the USB storage device, wait 10 seconds, and turn the Kronos back on.


7. The boot display ("Kronos") doesn't list the version until after the red progress bar is almost all the way right.  Then the OS Version will appear.

The first time I did this it didn't work and still said 1.0.4.  I went through the steps above again and the second time it seemed to work (the boot sequence flashes the "Disk" light differently in 1.5 as compared to 1.0.4).
