Hi, I'm using Atmega16u4 MCU and JTAGICE MKII device programmer. I have changed following parameters of makefile of DFU Bootloader -
MCU = atmega16u4
FLASH_SIZE_KB = 16
BOOT_SECTION_SIZE_KB = 4
Using Avr Studio and JTAGICE MKII I have generated hex file and loaded to the flash memory respectively. My question is that how I can understand the bootloader is working.
Before loading hex file I have connected the micro-controller through USB and it has shown ATm32U4DFU in "Device Manager" under "Unknown device" (since it has factory configured bootloader beforehand), but after loading hex file it shows "Unknown Device" under "Universal Serial Bus Controllers". If DFU bootloader hex file is working perfectly (I guess) it should show ATm32U4DFU under Unknown device!
I am using:
Any suggestions will be very much appreciable.
