Dear All
I want to store data in CF mass storage card with 64 GB space, So I have to used NTFS or exFAT file system to store. I used NXP Cortex - M4 processor and Keil u4 compiler, so we need NTFS or exFAT source code to attache them in my project. Is there any one to help?
Thanks
Is that true? I'm fairly sure I've formatted a 64GB card to FAT32.
Yes, it's absolutely true. In windows, you can format a 64GB ram in FAT32 but it reduces speed and windows will handle your work. FAT32 can max 32GB storage.
We need open source C code to attached them in uVision project. If we want to use Linux's kernel, it will handle this problem, but we don't want to use Linux. Consider we want to use Cortex-M4 processor that can not support Linux! I have searched a lot in Google. could anyone help me who has a valid experience?
FATFS definitely supports exFAT, used it here for 200-400GB microSD cards.
NTFS will likely need you to license a third party library.
Both will likely incur license payments to Microsoft

You're lucky this software hasn't closed out the thread with my late post.
It was listed as a related post, lacked an answer, and still likely to get random hits when Googled. Playing the odds here..
It's on my todo list :)
Best I could do in a pinch - congrats on raising this post back from the dead.
