Hello, I will ask Keil tomorrow, but have you noticed that you can build your FlashFS application using Microlib, 'finit' will return "OK", but 'fopen' will fail? I have spend 9 hours today dismantling Keil's stuff until a small prototype (RTX + FlashFS) revealed this grim reality... I did not see any reference to that in the documentation, even though somebody here talked about it (I just recalled that)...
Microlib is an optimized library for embedded single chip solutions.
