Hi all,

One of the several things sadly broken (and therefore clearly untested) with the LPC4357 LPCOpen2.04 build for Keil is FatFS which doesn't work with Long FileNames (LFN mode).

Thankfully they also produced an App Note a while back which describes how to do it properly:

Following these steps, and in particular the configuration settings described therein, has allowed us to use FatFS with LFN support except mysteriously when listing files, which still only works in 8.3 format.

Hope this helps!

Richard
