Bug Fix Patch mxc_nand-Fix-OOB-handling.patch for phyCARD-S PD10.2.0 (BSP001)
-----------------------------------------------------------------------------

This patch fixes a bug in the NAND-flash driver for phyCARD-S with 
64MB NAND Flash. phyCARD-S with 128MB NAND-flash are not affected 
by this problem. The phyCARD-S BSPs PD09.2.0R3 and earlier are also 
not affected by this problem.

The NAND-flash driver has a problem handling the OOB of NAND-flashes
with 512 byte page size. The Bad Block table is increasing every boot
cycle and it seems that the NAND-Flash is corrupted. The
mxc_nand-Fix-OOB-handling.patch fixes this issue.


How do I apply the patch to my phyCARD-S PD10.2.0 BSP?
------------------------------------------------------

1. Follow the instructions of the 'QuickStart Manual OSELAS.BSP() phyCARDs' Chapter 1
to set up the required working environment and Chapter 2 to build the phyCARD BSP.

2. Change to the main BSP folder
 cd OSELAS.BSP-Phytec-phyCORE-i.MX27-PD11.1.0

3. Copy the patch to the patch stack of the linux kernel
 cp /path/to/mxc_nand-Fix-OOB-handling.patch configs/phyCARD-S-2010.08.0/patches/linux-2.6.33.7/generic/

4. Add the Patch to the series file:
 echo mxc_nand-Fix-OOB-handling.patch >> configs/phyCARD-S-2010.08.0/patches/linux-2.6.33.7/generic/series

5. Clean the kernel and rebuild the Kernel with the patch.
 ptxdist-2010.08.0 clean kernel
 ptxdist-2010.08.0 targetinstall kernel

6. Now you find the new kernel with the bugfix included under:
 OSELAS.BSP-Phytec-phyCORE-i.MX27-PD11.1.0/platform-phyCARD-S/images/linuximage

Now update the kernel on your module.


I updated the linux kernel but the problem still exsist.
--------------------------------------------------------

In this case you should erase the complete flash (erase size 0x4000000) with ATKToolkit.
Now flash the bootloader, the rootfs and your new built kernel on the module.
