Hi ,
I am using video related application on OMAP board. When I am running from NFS server the Display is getting created and I am not facing any issue but when I am running the same application from
1.the flashed filesystem and mounting the card alongwith the application and
2. From MMC Card filesystem and application then I am facing the following errors
: page allocation failure. order:10, mode:0xd1

However on MMC card 1.5 GB is free, what NFS Filesystem makes the difference to run the Video Related applications.What is the fix? Is this kernel related issue. I am using flashed kernel throughout which I got with SDK 1.0.2 Is this memory related isuue? Is there any release which fixes this issue?
