J-Flash
J-Flash is a PC software running on Windows (Windows 2000 and later) systems, which enables you to program the internal and external flash of your microcontroller via J-Link.

What is multi-bank programming support?
Multi-bank programming support describes the possibility to program different flash devices, present on the same hardware, in one Flash programming session. For example, if you want to use the internal flash of your target hardware as well as the external flash for the target application code, multi-bank programming enables you to download the target application into the internal and external flash in one flash programming session. The settings for both flash banks are saved in the same J-Flash project, so you will only need one project in order to program multiple flash banks.
Support for Atmel DataFlash, NAND flash, SPI-NOR flash
Since the connection of these flashes varies from microcontroller to microcontroller, there are always some modifications which are necessary, to get DataFlash/NAND/SPI-NOR flash supported on a specific hardware.
The J-Flash software comes with sample projects which allow programming the DataFlash/NAND flash on popular eval boards. If you have a hardware-design which is based on the one of the eval board, these sample projects should also work for your custom hardware.
If your hardware design varies too much, usually a custom RAMCode is needed which programs the flash of your target hardware. RAMCodes for custom hardware can be created on request. For more information about pricing and requirements for a custom RAMCode, please contact sales@segger.com. SEGGER also provides a RAMCode template which enables customers to write a custom RAMCode on their own. The RAMCode template is available on request.
