Briki board

[Roberto Bucher]

Hi

we have this little board (www.briki.org)

with 2 different cores:

MBC-WB01-BPN:
SAMD211 – ESP322 – EXT 64 Mbit flash3 – PCB Antenna4 – No Crypto5

SAMD211: ATSAMD21G18A ARM® Cortex®-M0+
ESP32: ESP32-D0WD dual-core Tensilica Xtensa LX6 running @240MHz

How difficult should be the porting of the ESP32 processor to NuttX? It 
is possible to use one of the Expressif configurations? What about the 
ATSAMD21G18A board?

Thanks in advance!
