    SEGGER Flash Loaders

    SEGGER has a history of writing highly performant flash loaders.

    The engineering team behind the flash loaders created techniques like the Turbo Mode, that enable writing at the highest possible speed by writing to flash and transferring the data in parallel. The flash programming hardware has been adapted to achieve the highest possible bus frequency on whatever target interface is being written to.

    The Flasher family of flash programmers uses the same ultra fast target interface logic as is used by the J-Link flash loaders for the debug interface. In addition, the Flasher family of production programmers can also address production programming interfaces.
