1.3.1 Model comparison
The following tables show the features which are included in each J-Link / J-Trace
model.
Hardware features
Software features
Software features are features implemented in the software running on the host.
Software features can either come with the J-Link or be added later using a license
string from Segger.
1
In order to use the flash breakpoints with J-Link no additional license for flash
download is required. The flash breakpoint feature allows setting an unlimited num-
ber of breakpoints even if the application program is not located in RAM, but in flash
memory. Without this feature, the number of breakpoints which can be set in flash is
limited to the number of hardware breakpoints (typically two for ARM 7/9, up to six
for Cortex-M) For more information about flash breakpoints, please refer to Flash
breakpoints on page 263.
2
Most IDEs come with its own flashloaders, so in most cases this feature is not
essential for debugging applications in flash. The J-Link flash download feature is
mainly used in debug environments where the debugger does not come with an own
flashloader (for example, the GNU Debugger). For more information about how flash
download via FlashDL works, please refer to Flash download on page 247.
