HI,
This is Venkat and working on ST ARM , STM32f103ZE evaluation board. We have bought MDK-ARM and RL_ARM. I am trying to set up file system on M25P64 SPI serial flash but not able to do it. fopen{"S:file","w"); failing with return value NULL. I could not find code for fopen (definition) and I could see __fopen in _fs_fopen.c file provided with RL_ARM library. I am not sure how the fopen call reach __fopen and assuming that the RL_ARM library internally do this.
I have created FS_SPI_FlashDev.h as per M25P64 and corresponding FS_SPI_FlashPrg.c and followed the ARM documentation for creating the file system with SPI low level driver functions.
If any one has SPI serial flash file system example please help me.
Thanks, Venkat
