Good news! CONTROLLINO team has released a new board support package which hopefully fixes the issues with the “bricked” devices – some rare cases when there was not possible to upload a sketch anymore. The board support package includes a new bootloader for MINI – version 02. And it also includes all necessary information for Arduino IDE to able to program this bootloader.
All CONTROLLINO MINI devices produced from now already include the new bootlader.
The users interrested to upgrade their MINIs have two possibilities
use Atmel Studio and Atmel ICE programmer (only for experienced users, Atmel ICE is quite expensive)
use Arduino UNO as ISP programmer – you just need Arduino UNO, USB cable, few wires and THIS TUTORIAL!
Note: In principle is is possible to use any 5V Arduino board instead of the UNO. See this arduino guide for more details.
Update your Arduino IDE with the latest CONTROLLINO board support package
Make sure that you have version 3.1.0 or later. You can find this information in Arduino IDE – Tools – Board – Boards Manager
