LFN - Build Error and Does not Work

user4311498

Hello,

I am developing an application, and would be good to use LFN in fatfs.

I already altered the flag to 1 and rebuild the FATFS library

When I tried to use Long File names it didn't work. And I don't know why. And now, i cannot even compile the fatfs library, because I have the following error also when the LFN is set to 1, 2 or 3:

undefined   first referenced
symbol         in file
---------       ----------------
ff_convert /Applications/ti/cc3200-sdk/third_party/fatfs/ccs/Release/fatfs.a<ff.obj>
ff_wtoupper /Applications/ti/cc3200-sdk/third_party/fatfs/ccs/Release/fatfs.a<ff.obj>

Can anyone help?

Many thanks

Hello,

I have not tested this example but I can freely compile the various _USE_LFN options.

I modified it inffconf.h.

Hello,

The compilation of the library itself works well but it fails to link the application to the library becasue of these missing symbols.

You are right as those symbols are not implemented in the example code.

For now, there is not much I can do besides open a bug internally for it.

Limitations for this example are that it does not work with LFN other than 0.

Yes, already saw that. I managed to put it into work, by adding the fatfs directly from the website, the problem is it now takes to much space in memory.
