MFS on nandflash, MQX3.7

[Rpalenci]

Hello, 

I have a twrmcf54418 and I am trying mount mfs on a partition of 
nandflash. 

    mqx_status=_io_part_mgr_install ( nandflash_hdl, "PM:", 
528); 
    dev_fd_PM = fopen("PM:", NULL); 

Function fopen always return NULL. 
Is it possible mount mfs on one partition of nandflash?

Hello,

I would like to update this thread, since MQX 4.0 release notes state the following:

<<

Ready for new Freescale NAND Flash File System library.

o The MQX 4.0 has been tested with the new FFS library which implements the wear leveling algorithms and support for on-chip NAND Flash controller.

o This library enables the MFS filesystem to be installed and used on top of the NAND Flash memory devices.

o The FFS library is available as a standalone installation package.

>>

Unfortunately, I was not able to find any link to a so-called "Freescale NAND Flash File System library". All I could find where links to third-party commercial solutions.

Hello,

I can´t find the FFS patch for MQX 4.0. The link above does not work for me. It says restricted access.

Where I can find it?

Best regards.

Oscar.

Hello,

I am stopped on my project because this problem. And now, I beginning to think it is impossible mount a filesystem with MQX on nandflash.

Nobody knows anything  about it?

Thanks in advanced.

Best regards.

Hi Rpalenci,

MFS (FAT) is absolutelly not suitable system for flash drivers. Unfortunatelly, there is no alternative.

Can you find out the reason it failed?
