Hi,
I am currently working with a custom board built around the AT91SAM9263 microcontroller. The board make use of external Dataflash for permanent storage of the application (later transferred to an external SDRAM for execution). The Dataflash memory is of type AT45DB642D and is connected to the MCU by the SPI0 bus. To be able to access the MCU (and in turn the memory) I am using an SAM-ICE JTAG emulator with the latest J-Flash software (v4.08l). To flash the Dataflash I am using J-Flash ARM, but without success: at connection it says "Could not find any flash devices". I am using the option "Automatically detect flash memory" since the AT45D/DB is not among the list of supported flash devices. Can't I flash simply because the memory I am using isn't supported? If so, is it possible to add support for it?
Best regards,
Robert
