Can't burn bootloader on MT_D21E

mattairtech / ArduinoCore-samd

This is a fork from arduino/ArduinoCore-samd on GitHub. This will be used to maintain Arduino support for SAM D|L|C (M0+ and M4F) boards including the MattairTech Xeno Mini and the MT-D21E (see https://www.mattairtech.com/). It adds support for new devices like the D51, L21, C21, and D11. It also adds new clock sources, like a high speed crystal or internal oscillator.

I tried to burn the bootloader to the dev board using a Segger J-Link in Atmel studio. I can read the board signature and fuse with no problem. The flash is written successfully but then nothing happen when I touble tap. Here are the fuse settings: Here is the flash write interface: burn bootloader

I downloaded the binary directly from this repo and triple checked the board/mcu to make sure they match.

Not sure what else to try. Do you have any idea where that could come form?

OK I figured it out. I downloaded the specific bin file directly from the github page instead of downloading the whole repo as a zip file and then loading the file...
