[En-Nut-Discussion] Why don't we use compile option -O2 for arm ?

[TicTac]

Hello !
May I ask what board are you developing on ? I'm trying to get it work 
on arm LPC2138, but it always hangs at second call to NutThreadSwitch
when it tries to update "runningThread->td_sp" variable :(
How does your memory map look like ?
Regards,
Paul Melnarowicz
