Hello,

I've made necessary changes to MySensors 2.4.0-alpha in order to work on Odroid-N2 SBC running Ubuntu 21.04 with 5.13.0 kernel
Library would have worked if every reference to pin number was at least uint16_t (not uint8_t, like it is). That's because Odroid-N2 have >2^8 pin numbering, and GPIO ranges in 460-490 decimal.

I've made my fork@github and pushed odroid-n2 required changes version.
Using polling (non-IRQ) mysgw drains 1.0% cpu time.
Still waiting for interrupt issues to resolve with HK team - hopefully soon.

@Norton yep, it works in polling mode (~1% of cpu).

Maybe diggin a topic a bit, but as for June 2021 :

In library file MyHwSTM32.h one line seems to be lost :

#ifndef MyHwSTM32_h
#define MyHwSTM32_h

#include <IWatchdog.h>
#include <itoa.h>
#include <SPI.h>
#include <EEPROM.h>   <<--- this is necessary to compile agains BluePill

and something like this in platformio.ini

[env:bluepill_f103c8]
platform = ststm32
board = bluepill_f103c8
framework = arduino

upload_protocol = stlink
debug_port = stlink
debug_tool = stlink
monitor_speed = 115200
monitor_filters = time, default

Just to keep you entertained.
Cheerz.
