You can override default Atmel ATSAMR21-XPRO settings per build environment using
board_*** option, where
*** is a JSON object path from
board manifest samr21_xpro.json. For example,
[env:samr21_xpro] platform = atmelsam board = samr21_xpro ; change microcontroller board_build.mcu = samr21g18a ; change MCU frequency board_build.f_cpu = 48000000L
Atmel ATSAMR21-XPRO supports the next uploading protocols:
Default protocol is
You can change upload protocol using upload_protocol option:
[env:samr21_xpro] platform = atmelsam board = samr21_xpro upload_protocol = cmsis-dap
Debugging - “1-click” solution for debugging with a zero configuration.
You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.
Atmel ATSAMR21-XPRO has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
