Hello TI,

I am using fatfs for file open, read, write etc.

I have done successfully short file open, write and close.

but unable to open long file name.

I have already change the value of FF_USE_LFN to 3.

but unable to open file.

any more setting is required for LFN?

Thanks and Regards,

Mubin

The fatfs is a third-party module that have partial support by us.

We test it in the default configuration only but changes are possible (updates such as the FF_USE_LFN will require recompiling the module, before building the app).

You may refer to the following non-cc32xx threads that may provide more guidance.
