i have a MCB STR9 keil board . can i port linux code to it. help me.
There are 2 distinct questions here:
(1). Is it possible?
(2). Can you do it?
Since you asked the question in the form that you did, then the answer to (2) is most probably "No" - if you had the necessary skills & experience, then you would know the specific questions to ask regarding the capabilities of this platform...
There is plenty of material available on Linux porting if that's a field that you want to get into...
