1.0 Requirements

  • Programming utility KitraFirmwareUpgrade_VX.out builded for Artik5
  • Firmware you want to program (Kitra_VX.bin)
  • No application using Kitra520 serial must be running

Check the main repository if you miss something.

Warning: If your Kitra520 board has a firmware version 0, it may be unsafe to upgrade the firmware because when going into bootloader mode Kitra shutdowns Artik too fast, without allowing a safe power down. New versions have a 20 seconds delay to allow a power off, but if a process is stuck an unsafe shutdown may happend even with new firmware version. What can happend is a very rare file system corruption, so backup your data before doing any update. If that happended you can re-flash your rootfs via fastboot/usb, check reflash fedora via fastboot

2.0 Steps

  1. Copy the Kitra_VX.bin and KitraFirmwareUpgrade_VX.out binaries on Artik, using ssh or ftp.

  2. Run

chmod +x KitraFirmwareUpgrade_VX.out
./KitraFirmwareUpgrade_VX.out /dev/ttySAC3

You will get the current firmware verison and will be asked to reboot the system to go into bootloader mode. Shutdown is already perfomed by the application.

  1. Press 'y' and ENTER

  2. Wait the reboot to finish and log into the shell again

  3. Close again any application that may be using the Kitra serial

  4. Run

./KitraFirmwareUpgrade_VX.out /dev/ttySAC3 Kitra_VX.bin

  1. If you see "Update done reboot the system and kitra" that means that the upgrade was successuful

  2. Shutdown Artik

  3. Power off Kitra with a long press (10s) on the user button

  4. Restart Kitra with a short press (2s) on the user button

3.0 FAQ

I do not hear any beep during Kitra power off

That's normal, the bootloader does not handle the buzzer.

I do not hear any beep after the update

The upgrade failed or you are still in bootloader mode.

How can i go out from bootloader mode?

Shutdown Artik, Kitra and restart Kitra with a short press on the user button. If Kitra has a valid firmware programmed it will run that, if not it will stay in bootloader mode.
