Posted · Restoring Firmware after replacing MCU on Ultimaker 2.1.1 board

I have just replaced the MCU chip on my Ultimaker 2.1.1 main board and am looking to reload firmware. Can someone provide guidance on installation of the boot loader and firmware? I am familiar with the ISCP interface and have an AVR but I need to know where to pick up the correct boot loader image that will allow me to use Cura to install the most recent firmware.

    Hmmm, I would think it uses the Arduino bootloader for the equivalent Arduino board that has the same MCU since Cura is able to update both the UM2 and UMO. Possibly the bootloader for the Arduino Mega 2560 R3 which is used in the UMO? Is the MCU an ATMEGA?
