I am new at this (my first ARM). I am using a OLIMEX AT91 SAM7-EX256 development board and i am trying to write info to a file from a task periodically. I heave tried to configure Elm Chan’s FATFS in order to do this, but with little success. I managed to get it to mount the fs and open/create files, but after writing some characters in a file, it doesn’t work anymore. Has anyone configured and used FATFS for this board? I am also a little confused about the correct SPI settings as i am using the LCD also. Please help a newbie in need f you can.
This will show you how you can integrate FatFS with FreeRTOS http://www.freertos.org/Free-RTOS-FAT-file-system-USB-LPC2148.html I think you will have to Google for the SPI drivers.
