#ATMEL ICE DRIVER HOW TO#

After plugging in the Atmel-ICE to the clone Nano board, I could not get AS7 to read the device ID of the CPU or its fuses. I was a little taken aback by this because there is a 5V and ground connection on the ISP. I then came to realize that the Atmel-ICE apparently also needs the board to be powered externally (from the USB connector, presumably), or the target power LED will not light.

This confirmed to me that Atmel-ICE was communicating with my computer (i.e., the proper drivers were installed with the AS7 installation). The first thing it told me was that my Atmel-ICE needed a firmware upgrade, which it completed. The flat ribbon cable with the 10-pin end was connected to the AVR connector on Atmel-ICE, and the 6 pin ISP connector was connected to the ISP connector on the Nano with pin 1 properly connected to pin 1 of the Atmel-ICE connector (the pin 1 location is a little weird on the Nano). After I installed AS7, I tried to program one of the Nano clones using the ISP connector and the debug-Wire mode. I also don't think that the CH340 chip is a factor when programming with Atmel-ICE. I don't think the bootloader is a factor when programming with Atmel-ICE. After that the Nano clone programmed perfectly. Without that, the Nano clone would not program. I tested a few of the clones (on Windows 10) using the Arduino IDE after fussing around and finally setting the IDE to use the 'Old Bootloader'for the Nano.

I recently purchased 5 Chinese eMakeFun Nano clones with the CH340 USB chip for the purpose of trying to learn how to transition from the Arduino IDE to the AS7 and the Atmel ICE debugger. I posted this in another area of the forum before I saw this area, which is probably a more proper location for the post.
