File System on Cortex M3 (LPC1768)

Dhaval Solanki
Note: This was originally posted on 21st September 2012 at http://forums.arm.com

Dear All,
I am new to programming rtos on LPC 1768. I want to learn and hence implement filesystem on lpc1768 but am unable to figure out where to begin with.
I am currently studying FAT32 filesystem but am unsure whether i am on the correct path or not. Kindly advise.

Few doubts:
Can we implement FAT32 on LPC1768?
Should i implement FAT32 or ext2?
Are any libraries readily available? If so, how do i acquire them? (any download links?)
Are there any example codes?

Regards,
Dhaval Solanki

    Hey, there's a FAT system for reading SD and MMC cards thats not to heavy and can help you figure out what you need. However, you'll need to configure your LPC in order to use the SPI (MISO, MOSI, SCLK, CS) because these are needed when interfacing these types of storage. It is totally free. The website isn't too complicated and you'll figure out where to download and everything but if you have questions, feel free to write me a private message. I have use this Fat system with a cypress Psoc5 chip which also based on a Cortex M3 core.
    Have fun!

    Dear Sasa,
    Thank you.
    The link given by you is very helpful. Will study.
    I found that we can implement flash file system to interface SD card.
    Will study in detail, further and then decide.
