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



Error opening filesystem: UNKNOWN ERROR !!!


For MQX 3.8.0 I've found in Release Notes ( 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 ( 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,
