Thanks for continuing doing this.

Can you say about how hard it is to port GNAT RTS to a new board, given
a reasonable C environment for the board?  How much code space and ram
is required?

Boards I'm interested include the cheapo "Blue Pill" (Maple Mini clone,
i.e. Cortex M3 with specs 64k of flash and 20k of ram, though most of
them seem to have 128k of flash instead of the 64k specified),
Adafruit's SAMD21/SAMD51 boards (Trinket M0, and Itty Bitty and Feather
M0 and M4), and PJRC's Teensy boards.

I'd be happy to send you a Blue Pill if you want one.  They are similar
to this: https://www.banggood.com/-p-1058299.html

They are under 2 USD each on Aliexpress though I can't give a url there
because of how their ordering system change.

Thanks!
