Upgrade cleo 35 from 1.1.1 to 2.1.2
« on: April 05, 2018, 08:34:56 PM »

I try to upgrade many Cleo following this procedure:
- Use Cleo PC tools to upgrade to 2.1.2 =>OK
- insert SD card with content from Zip file and run LoadFlash.ino then

i see  "EFLASH" progress bar followed by a screen calibration (request to touch screen 3x)

On my first Cleo35 that end well with the message "Load complete"
On my second Cleo35 i got blue screen with the text below:

returned error -14 :assertion
Cannot open file “@System\cal.bin”

And the screen is unusable (touchscreen not reacting)
What can i do now?
