samples/fileio - ram disk testing failure in case of restoring disk image from NAND to SRAM.

[Hoefle Marco]

Hello Thomas,

How do you create the FATFS image? I have also an issue with FAT image linked into the application.

In my case getcwd() is not working correctly after being deeper than 3 subfolders.

But the rest seems to work ok.

I filed this bug

https://www.rtems.org/bugzilla/show_bug.cgi?id=2190

with a test case.

 

For us only Fat12 or FAT16 work, FAT32 didn't work with the image generation process described in the bug report.

Best regards,

Marco

Dear Sebastian,

 

NAND flash is only used for storing FAT32 disk image. 

After this disk image of flash is copied on SRAM by bootloader, RTEMS DOS file system is mounted for disk clone image on SRAM.

 

Best Regards,

Thomas

FAT32 is unsuitable for NAND flash devises unless you use a flash translation layer.
