Using Debuggers Other Than Segger J-Link for FX3™ - KBA85504
Can I use debuggers other than Segger J-Link to debug the FX3™ code?
If these debuggers (such as ST-Link/V2) use GDB, they can be configured to debug FX3 using the GDB initialization commands given in page 160-161 of the FX3 Programmer's Manual. Change the port to which the server connects by changing the first line in the initialization commands (target remote localhost:TCP_PORT_ADDRESS).
