Hi, I am looking to upload a UART bootloader which is provided by microchip( AN2634 application note) on my ATtiny806. Currently I flash my Firmware using Atmel ICE and UPDI interface. Now I am looking to flash the firmware using a USB to UART chip (MCP2200). How can I add that bootloader provided by microchip on my application firmware and what are the changes I need to make in that bootloader for ATTiny806? I am using IAR IDE.
