Hi,

Currently on OMAP-L138, m25p80 SPI flash can be accessed using MTD interface. So you can do flash_erase and then mount and copy the required files onto the MTD partition.

If you absolutely need to access it from an application and have full control over the Flash data (which is not the case with MTD), then you could expose your SPI bus with SPIDEV and perform SPI transactions directly from your application through the SPIDEV interface.
