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

[YoungDong Yoo]

Hi All,

I have a question.

Unlike other cpus (except ARM),

For me (arm developer, gcc user), I can't use compile option -O2
(optimatize). 

When I use O2 option, the board is down. 

I would really appreciate any help !
Best regards,

YoungDong Yoo
