How to extend file name size in KSDK 1.3 USB Host MSD-FATfs

[MAPC]

Hello,

In the default configuration, KSDK 1.3 USB Host MSD FATfs library allows me to create files in the format 8:3. In other words, the file name must have up to 8 characters for the name itself and 3 for the extension.

I need 16 characters for the file name and 3 for the extension. Is that possible? Which settings should I do?

IDE: KDS 3.0

MCU: MK22FN512VLH12

Thanks and best regards,

Marco Coelho

Hi Marco,

Please follow the following steps to add long file name support:

1.#define    _USE_LFN    3 in ffconf.h

2.#define _CODE_PAGE    437 in ffconf.h

I have tested based on host_msd_fatfs demo on frdm-k64f, it runs well. Please refer to the following snapshots for more details.

Hope that helps,

Have a great day,
Kan
