Hi All,

   We are using PPC8248 provided by freescale and the kernel  2.6.10. I believe we have cache problem.

  We are allocating DMA buffers in our driver. If we increase the DMA buffer size the board hangs/halts(when try to load more applications).

  If we reduce the DMA buffer size, then we can run all our applications.

   Is there any way I can get around this problem.


Thanks
Jayasri
