Generally a GDB client does not support SWO. But luckily, the J-Link GDB server is able to work around this and send SWO data to a socket. This article is a step-by-step guide about how to use SWO with J-Linkg and a GDB client.
Contents
Default settings
If not set differently, J-Link GDB Server will use default settings:
- Telnet port: 2331
- SWO data port: 2332
Example with a MK22FN512xxx12 device using putty (default ports)
This example shows how to setup J-Link GDB Server, a GDB client and Putty for SWO. It was created by using default port settings. Further information about setting different ports and more can be found in UM08001. In this example the following applications were used:
- J-Llink GDB Server V6.54a
- ARM GDB client (V7.3.1)
- Putty (V0.70)
Setting up the J-Link GDB Server
- Open the J-Link GDB Server
- Set all options as required:
- Start the J-Link GDB Server
Setting up the GDB client
- Open a command line GDB client
- Connect to the J-Link GDB Server. This can be achieved via these commands:
target remote :2331 monitor SWO EnableTarget 0 0 1 0 c
Setting up putty
- Open putty
- Setup putty as required:
