Bootloader for different SAMD21 versions

Official Hardware Classic Zero

Hi,

Developing our own board with a SAMD21 and thinking of going down to a simpler version. (32 pins, 8kB RAM 64k Flash) SAMD21E16.

Seen in this other thread (Atsamd21g18 Bootloader - Arduino Zero - Arduino Forum) that the bootloader was changed for the version with more pins and seems easy to change to the version with less pins I imagine.

The question is if the difference in memory size also affects the bootloader and should it be changed for this other version.

Hi,

Take a look at the Rabid Prototypes Tau board and software package.

Hi,

Looks very interesting.

Do you know if there is a bootloader available for this SAM version?
