Install Fedora 24
This guide examplains how to program the board through USB instead of SDCARD. Consider that if something goes wrong the only way to reflash an Artik520 is through SDCARD by using its evaluation board.
- Fastboot tools here
Download the following: Kitra520-os2.0-v1
tar -xvf Kitra520-os2.0-v1-USBFLASH.tar.gz
cd Kitra520-os2.0-v1-USBFLASH.tar.gz
Extract it using 7zip.
DNow shutdown Artik and Kitra (if you are stuck just keep the user button pressed for around 8 seconds, until you hear the beep sound stopping) leaving the debug usb cable connected.
Plug the battery usb cable to the pc, this will be used as OTG to flash the new device tree.
Power on Kitra by pressing the user button for 2 seconds and press ENTER to get into the u-boot prompt.
type fastboot
sudo ./flash_all_by_fastboot.sh -o .
First check if driver were installed correctly inside Device Management, if you see the following warning:
Then you need to select manually an Android ADB interface driver.
Right click on Android 1.0 - > Update driver -> Find in my computer -> Choose from list!
If you see something slightly different then "Android Device", like "SAMSUNG Android Device" or "ASUS Android device", they will work too.
After that select any "ADB Interface".
