[En-Nut-Discussion] Minimalistic stack settings

[Henrik Maier]

Hello forum,

I am trying to find the smallest possible stack settings for Nut/OS 
4.0.x or 3.9.x which are still known to work.

Currently there are 6 stack size configuration values:

NUT_THREAD_IDLESTACK
NUT_THREAD_MAINSTACK
NUT_THREAD_TCPSMSTACK
NUT_THREAD_SNTPSTACK
NUT_THREAD_NICRXSTACK
NUT_THREAD_AHDLCRXSTACK

Maybe somebody tried to play with these settings and can tell me which 
values are known to work and which settings certainly will lead to 
unstable systems.

The stack size issue matters for systems based on the AT90CAN128 chip, 
where total stack size is limited to 4 Kbyte.

Regards

Henrik Maier
