Hi,
I am using K20 series micro controller in my project. I have a PSRAM interface to the K20 using the flexibus. I need to store the files from USB into the PSRAM in the same format as in USB. I want to format the PSRAM for FAT12/16 file system.
Does MQX file system supports this feature?
Thanks in advance.

It's included as part of MQX after you install it on your computer. The full path name would be <mqx_install_directory>\mfs\examples\ramdisk
MQX can be downloaded from here: http://www.freescale.com/webapp/sps/site/overview.jsp?code=MQXSWDW
I believe that would be possible since there are examples of doing that with MRAM on the TWR-MEM tower board over the flexbus. Take a look at \mfs\examples\ramdisk
There are format IOCTL commands in MFS, and you can see the code used by the ramdisk example to format that memory in \shell\source\mfs\sh_format.c
