	Hi everyone, i'm new here. I searched a bit on the internet on how to solve my problem: I have an arduino MKRZERO and i'm trying to program it in Visual Studio 2017 with Visual Micro plugin and Arduino 1.8.9; i bought Atmel ICE programmer, but when uploading it gives "error at91samd21g18.cpu clearing lockup after double fault" Uploading bootloader works, and the strange thing is that after trying to upload my program and failing and loading bootloader, the previous program starts running! I wish to get full debugging on this setup, for example i even don't know what to choose under vMicro>Debugger menu, is first of all supported? Thank you

	Please post the info requested in yellow above so that we can see more clearly what you are trying to do and with which settings enabled. Upload Thanks, currently the Arduino definitions do not come with a reliable ICE programmer for upload. We will be releasing a version of visual micro over the comming few days that extends the Arduino programmers list with a full range of programmers. There are also some new tool bar options to make this quick and easy to select. Debug You would simply pick the ICE debugger from the Debugger menu or tool bar and also probably set Optimization to "No Project or Libraries" So for now use normal serial/bootloader upload along alongside ICE debug and enable notifications in the Releases section of this forum so that you get to hear about the new release over next few days.

	Was there ever a resolution to this problem? I am having the exact same symptoms with an Adafruit Gemma M0 (SAMD21) using Atmel ICE programmer. Burning the boot loader again causes the prior program load via programmer to start running. The COM port is not working to upload even after burning the bootloader.

	Can you attach the logs requested at the top of the page, and also enable the vMicro > Uploader > Verbose option? This is so we can fully understand which settings are enabled and which programmer is in use for burning the bootloader.
