Is somebody working on a driver for SAM9 to program SPI dataflash? If not, will start next week. Regards Joern |

Hello Joern, there's a patch for SPI flash with CS EP93xx chips in the patch tracker: http://developer.berlios.de/patch/?func=detailpatch&patch_id=1462&group_id=4148 I haven't worked with dataflashes so far, but I supose there's some kind of standard for programming these devices? If possible the code should be split into a generic part that handles the programming algorithms, and device specific drivers for the SPI controllers, similar to the way NAND is handled.

After reading the datasheets of the dataflashes it is possible to split the generic and the device specific functions. I'll create a dataflash.c/h and a sam9_dataflash.c/h. Regards Joern |

That's good as I was going to add support for the str75x boot spi flash.
