NEW GUIDE: How to Program SAMD Bootloaders #SAMD21 #SAMD51 @microchipmakes
Do you have a bricked Adafruit SAMD board that won’t boot into CircuitPython, or show up as a boot volume?
Are you building your own SAMD board and want to flash our UF2-SAMD bootloader onto it?
This new guide covers wiring a J-Link to a SAMD board, flashing the bootloader, and (optionally) installing the latest CircuitPython build.
This process does require extra hardware and some software installation time. It is unfortunate when a microcontroller’s firmware is corrupted – it does not happen often. But, rather than buy a new board and have one sitting, this process will get your original board back to 100%.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
