HI,

Need help in FatFS in SD card using LPC4350 controller. file system is mounting with f_mount, but not able to open any file with f_open.

need to use disk_initialize() for intilization. in the sample prjts directly used f_mount to mount the file system.

f_mount is called at the time of sysinit(). am need to call disk_initialize().disk_status(),disk_read() before to f_mount.

Please sugest me where i did mistake.

regards,

Viswanath K.

Viswanath,

sysinit() is NOT for such complex functions as f_mount is!

At sysinit() time, the C runtime library is NOT initialized! All C variables have not been set up! C++ global constructors are not called.

So, please move any complex code to the beginning of main()!
