Did you add the generic FLASH layer? FLASH drivers come in at least two parts - the generic layer and a hardware specific driver. Also many hardware drivers are built of two parts - the generic driver for a chipset and the platform specific driver. You'll need to make sure that all the pieces have been loaded and enabled. Normally, if you configured your target correctly (in ecos.db), just adding the CYGPKG_IO_FLASH will be sufficient to enable everything. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
