Flasher Arm - Segger J-Link User Manual

1.3.10 Flasher ARM

Flasher ARM is a programming tool for microcontrollers with on-
chip or external Flash memory and ARM core. Flasher ARM is
designed for programming flash targets with the J-Flash soft-
ware or stand-alone. In addition to that Flasher ARM has all of
the J-Link functionality. For more information about Flasher
ARM, please refer to UM08007, Flasher ARM User's Guide.
