I am trying to run the nandflash and mfs_nandflash examples on a TWR-K60F120M Rev C board. I able to compile and run the examples, but they don't work as expected (details below). I'm using Codewarrior 10.4, MQX 4.0.2 and the MQX 4.0.2 Flash File System patch.
When I run nandflash, I get the "all bad blocks" problem described here: https://community.freescale.com/message/329282. The output I get is:
MQX NAND Flash Example Application

When I run mfs_nandflash, I get a similar problem to that described here: https://community.freescale.com/message/335118#335118. Everything seems to work until I try fsopen, which asks me to run repair. Repair claims to work, and then the next fsopen claims to work, but then "format a:" fails. I have tried multiple permutations, but that is as far as I get:
This is the Flash File System example, type help for list of available commands
If this is the first time you use the demo, you should run "nanderasechip" command first.

I tried to implement the solution described here: https://community.freescale.com/message/335118#335118, but the code snippet described doesn't exist in int_gpio.c. I found a similar snippet in bsp_cm.c and inserted line 4 from the above solution, but it didn't change the results.
Thanks for the help.
