Hello, I'm trying to start using Arduino on the SAML21 and I would like some guidance. So far, I've compiled SAM-BA for that CPU and tried burning a demo program from the Arduino IDE to the chip, but it gave an error saying that it was not able to find a bootloader.
I believe that, somewhere along the IDE files, I should enter the definition and support for the SAML21 processor, with it's correspoing chip ID, shouldnt I?? What would be the process of adding a new MCU from scracth to Arduino (a Cortex M0)?
Thanks in advance, Mauricio
