compatible with your SAMD51 boards ?

I would like to use a MSD Bootloader with your new SAMD51 boards ?
Is it planned that you update this code for using with SAMD51 ?

Sorry about the late reply. I completely forgot about this.
I will see if I can add support this week. I was thinking of eventually adding MSD support to the SAM-BA bootloader I include with the Arduino core, which already supports USB CDC, TTL serial, and Micro SD cards. It would then no longer be dependent on ASF. It might also make sense to add UF2 support (https://makecode.com/blog/one-chip-to-flash-them-all). BTW, ASF was not yet available for the SAM D51 last time I checked a couple of weeks ago (there is START support though), so that may make adding D51 support to the MSD only bootloader unlikely.

UF2 seems to be very interesting,
and is implemented already here for the SAMD51 somehow: https://github.com/Microsoft/uf2-samd21
see the "metro_m4" and "feather_m4" targets here: https://github.com/Microsoft/uf2-samd21/tree/master/boards

adafruit has its own fork:
https://github.com/adafruit/uf2-samdx1
with SAMD51 support as well ...

any news or new thoughts on that ?
