Building a safe and secure embedded world

Flasher Pro

Flasher Pro is a stand-alone JTAG/SWD programmer, that can be controlled without a PC after initial setup. The tool is designed for microcontrollers with on-chip or external flash memory and ARM7/9/11, Cortex, RX and PPC cores. It allows programming flash targets with the J-Flash software or stand-alone.

Flasher Pro additionally is equipped with full J-Link functionality (extensive feature set, large number of supported CPUs, and compatibility with all popular development environments). Flasher Pro connects to the PC via USB, Ethernet or via RS232 interface. It is running Microsoft Windows 2000, Windows XP, Windows 2003, Windows Vista, Windows 7, Windows 8 or Windows 10. It further has a built-in 20-pin JTAG connector, which is compatible to the standard 20-pin connector defined by ARM.


  • Ethernet interface
  • Supports internal and external flash devices
  • Wide range of devices are supported
  • Free software updates, 2 years of support
  • 128 MB internal NAND flash, used for storing configuration and data files
  • Serial in-target programming supported
  • Data files can be updated as mass storage or via J-Flash
  • Target interface: JTAG / SWD
  • No power supply required, powered through USB
  • Can be used as J-Link (JTAG emulator) with a download speed of up to 1 MByte/second
  • Programming speed typically between 30 KB/second and 1 MByte/second. Max. programming speed highly depends on target hardware and max. programming speed of the flash itself
  • ASCII command interface to control Flasher without the use of a PC program
  • Authorized Flashing allows to limit the number of flash programming cycles and to protect the Flasher against non-authorized access in case of external production
