Allright, I have NuttX origin/master built on FreeBSD and running on
ESP32-DevKitC :-)
For some reason uname -a shows release 10.4.0 not 12.0.0(99/dev whatever) o_O
The whole NuttX firmware build and flashing is faster than scripts
upload in MicroPython heheh.. and they fight for encoder / timer /
pcnt api for over two years.. I can also see CAN support.. maybe its
finally time to switch to NuttX for gooood =) =) =)
Now lets get to qencoder stuff ]:->
TANK U FOLKS! :-)
Tomek
ps/2: Does NuttX have some sort of FOTA mechanism so the signed
firmware could be updated remotely over WiFi/IP from some sort of
server with a fallback mechanism of
boot-from-last-that-worked-or-bare-nonalterable? :-)
