USB Host Integration on TWR-K21F120MA

[vikashkumar]

Hi,

I am working on USB host integration on TWR-K21F120MA board. I integrate example code of usb host on board. If i am not right example code using FAT32 file system. I have a problem, when i create folder/directory, it takes up to 8 character long only for folder/directory name, but i required more than that. And when i come in file name it follow 8.3 formula. when i give more than 8 character in folder/directory or file name, it does not create folder or file.

Hi

You need to enable "long file name" support if it is available in the FAT32 library.

For a ready-made K21F120 USB-Host MSD solution, which includes LFN utFAT and Linux workaround to avoid the Microsoft licensing requirement, see:
