What is J-Flash?
J-Flash is a PC software running on Windows 2000/XP
systems, which enables you to program your Flash EEPROM devices via the
On-Chip Debug connector (JTAG) on your target system.
A J-Link hardware, which connects via USB interface with the PC, is needed.
J-Flash 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, CHECKSUM, UPLOAD flash
content, and VIEW MEMORY functions of the software with your flash devices.
Purchasing a license will turn off the time limitation.
Features
- Works with any ARM7 / ARM9 chip
- ARM microcontrollers (internal flash) supported
- most external flash chips can be programmed (See list of supported
devices)
- High speed programming: up to 150 kByte/sec (dep. on flash device)
- Very high speed blank check: App. 16 Mybte /sec (depends on target)
- Smart read-back: Only non blank-portions of flash transferred and
saved
- Free 30 day trial version available
- Easy to use, comes with projects for standard eval boards
Easy to use
 |
After Installing the J-Link driver and
J-Flash, simply connect your J-Link to your PC and start the J-Flash
executable |

|
| We already provide project files for common CPUs and
Eval boards. If you do not find an existing project file for your
selected CPU, it is not difficult to write and save your own project
file. Choose Option|Project from the Menu and set the right settings
for your target hardware. |
Programming
 |
Programming speed depends on target system
and flash; app. 60-150 kByte/sec. |
Supported Microcontrollers
J-Flash can program the internal flash of the following
ARM microcontrollers. We are constantly adding new micros to this list.
If the chip you are looking for is not yet on the list, please get in
