What is J Link Programmer?
The J-Link BASE is a USB powered JTAG debug probe supporting a large number of CPU cores. Based on a 32-bit RISC CPU, it can communicate at high speed with the supported target CPUs. J-Link is used around the world in tens of thousand places for development and production (flash programming) purposes.
What pins are required for SWD?
In SWD mode, two pins are used for debugging: one bi-directional pin (SWDIO) transfers the information and the second pin (SWDCLK) clocks the data. A third pin (SWO) delivers the trace data at minimum system cost. The Serial Wire and JTAG pins are shared.
What is SWD debug?
What is SWD Debugging. SWD, also known as Serial Wire Debug is a 2-pin interface (SWDIO/SWCLK) of which it’s also an alternative JTAG interface that has the same JTAG protocol. SWD uses an ARM CPU standard bi-directional wire protocol, defined in the ARM Debug programmer.
What is Java Jlink?
jlink is a tool that generates a custom Java runtime image that contains only the platform modules that are required for a given application. Such a runtime image acts exactly like the JRE but contains only the modules we picked and the dependencies they need to function.
What is J-Link GDB server?
With J-Link GDB Server, programs can be debugged via GDB directly on the target, similar to when debugging with a direct connection. The application can be loaded into RAM or flash of the device.
Where can I find the manual for the GDB server?
The manual is available for download on the SEGGER website: UM08036 There are several command line options available for the GDB Server which allow configuration of the GDB Server before any connection to a J-Link is attempted or any connection from a GDB client is accepted.
Where can I find the latest version of GDB?
The latest Unix version of the GDB is freely available from the GNU committee under: GNU.org J-Link GDB Server is a remote server for GDB making it possible for GDB to connect to and communicate with the target device via J-Link.
What is the use of jlinkdevices XML?
This is mainly used for preliminary / special devices where a vendor ships a file to specific customers and this file defines new devices that are not publicly available yet. Passes the path of a J-Link script file to the GDB Server.
