4.2.7 J-Flash ARM (Program flash memory via JTAG)
J-Flash ARM is a software running on Windows 2000, Windows XP, Windows 2003 or
Windows Vista systems and enables you to program your flash EEPROM devices via
the JTAG connector on your target system.
J-Flash ARM works with any ARM7/9 system and supports all common external
flashes, as well as the programming of internal flash of ARM microcontrollers. It
allows you to erase, fill, program, blank check, upload flash content, and view memory
functions of the software with your flash devices.
J-Flash requires a additional license from Segger. Even without a license key you can
still use J-Flash ARM to open project files, read from connected devices, blank check
target memory, verify data files and so on. However, to actually program devices via
J-Flash ARM and J-Link / J-Trace you are required to obtain a license key from us.
Evaluation licenses are available free of charge. For further information go to our
website or contact us directly.
