compile android from android website

Hello,

I downloaded android kernel from android official website. I downloaded the
YAFFS2 file system from the YAFFS official website and I patched android to
support the YAFFS2 file system.

I compiled android and i got a zImage file. I loaded the zImage on Mini2440
and I used the file system from this website ("www.friendlyarm.net").


when I boot the mini2440, I got the following error ( see full trace on
attached file ). I worked on this probleme 2 weeks vainly. I couldn't fix
it ?



Please Help me to fix the probleme  :(   

Thank you very match

Hey Prakash A S, 

Have you gotten anywhere with the android source? 

Do you know if the android source recognizes the CROSS_COMPILE variable?

Hi Bill Sargent,
   The link I have given is the source they are maintain it properly. I
dont think other Android sources available for Mini2440.

Yes. It recognized the CROSS_COMPILE. You need to edit your Makefile.
