Yaa Erik I meant PXA255 not PXA250...
I cann't change kernel version ..it is required.still I will try to do that.
When we are cross compiling code for PXA255. all the device drivers will remain in /dev and newer one will be in /arch/ respective folder. May I right ?
If I will change mode from blocking to non-blocking , what will be the impact of that on application ?
Really need ur help on this..
