Keil Midlleware 6.3 (ARM Compiler) and File System

Robin Godefroid

Hi,

I just updated Keil software pack and installed new component "ARM_Compiler".
With this update I am not able to access FileSystem anymore.

Each time I call "fmount" function, return code is 9 (fsMediaError).

I selected Filesystem in "Compiler:IO"
I didn t change anything else in my code.

I use filesystem with USB and MCI in the same time, both fail.

My board is based on a LPC4337 processor and I am sure the design is correct (if I switch to Keil Midlleware 6.2 and remove ARM_compiler, everything works fine).

Filesystem example doesn t work either.

Did I miss something with this update ?
