I decided that the end address should be the last valid address of the flash, not the first invalid address. Attached (if i remember) is a patch which makes all the v2 device drivers consistenly set this correctly. Also the legacy driver interface now correctly sets the end address. I also added code which checks the end address against the block info when asserts are enabled. This will require a minor change to your dataFlash driver. Would you like me to commit the dataflash driver to the flash_v2 tree? Andrew
