FFS on NANDFLASH of TWR-K70 (MQX 4.0.1)

I want to install the Flash File System (FFS) from NAND Flash File System patch for Freescale MQX™ RTOS 4.0.0 on the NANDFLASH chip on the TWR-K70.

I'm running the included example and I'm getting the following terminal output:

Shell (build: Mar 21 2013)

Copyright (c) 2008 Freescale Semiconductor;


shell> fsopen

Unable to open nandflash device.


You must run Repair command

shell> nandrepair




Repair successfully

shell> fsopen


NAND flash device was opened.

shell> dir

Error, file system not mounted


Has someone got an idea what might be wrong. Are there any jumper settings necessary?

Is it correct that ENABLE_NANDFLASH must be set to zero in the BSP like stated in the nandflash_wl_config.h?

Thank you for your help!
