Hi,

 

I have tower setup with TWR-K60F120M and TWR-MEM boards and I'm trying to run demo.c program from mfs_nandflash_twrk60f120m. After opening file system with fsopen, I've got response:

 

shell> fsopen

Unable to open nandflash device.

 

You must run "nandrepair" command

shell> nandrepair

 

Repairing...

Error opening filesystem: UNKNOWN ERROR !!!

 

For MQX 3.8.0 I've found in Release Notes (http://cache.freescale.com/files/soft_dev_tools/doc/support_info/FSL_MQX_TWRK60F120M_RELEASE_NOTES.pdf) information that:

- When using Nand Flash module , remove MEM board from the tower due to the hardware conflict between Nandflash Module and FlexBus Module

Besides, I've also found information about disconnecting FlexBus (https://community.freescale.com/thread/309185) by disconnectingJ11 and J16 jumpers. Unfortunatelly it didn't help.

 

Important note is that alone TWR-K60F120M module works fine.

Do you have any idea what could be done ?

 

Thank you,

Maciej Wdowiarz-Bilski
