J-Link is a small USB to JTAG debug
device, designed for ARM cores. It connects
via USB to the Windows PC host.
J-Mem, a small (app. 50 kb) stand-alone
application for Microsoft Windows 2000 and
Windows XP is included. It requires a J-Link
connected to the USB port and an ARM
system connected to J-Link via the JTAG
interface.
J-Mem displays memory contents of ARM-
systems and allows modifications of RAM
and SFRs (Special Function Registers)
while target is running. It makes it possible
to look into the memory of an ARM chip at
run time; RAM can be modified and SFRs
can be written. The type of access for both
read and write access can be selected to
be 8/16/32 bit.
It works nicely when modifying SFRs,
especially because it writes the SFR only
after the complete value has been entered.
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 device, 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.
