Can not connect to J-Link via USB. Applies to: Answer Information in this knowledgebase article applies to: • MDK-ARM • J-Link and J-Trace debugger SYMPTOM I try to debug an ARM7/9 device with uVision Debugger via J-Link.

But starting a debug session or a flash download always fails with the following message in the Build Output window: Can not connect to J-Link via USB. CAUSE The J-Link device is probably configured for a J-Link USB ID other than 0.

Due to that, it can't be recognized by the uVision J-Link Debugger driver used for ARM7/9 devices. RESOLUTION Configure the J-Link for USB ID 0. This can be done with the J-Link commander tool found in the MDK-ARM installation directory C: Keil ARM Segger JLink.exe. This will identify the J-Link with ID different than 0 and when connected, provides a command 'usbaddr' to change the ID: C: Keil ARM Segger>jlink SEGGER J-Link Commander V4.36l ('?'

J-Link> After reconnecting the J-Link unit to the PC, debugging the ARM7/9 device with J-Link via the uVision Debugger should work. Please note that also the uVision J-Link Debugger driver used for Cortex-M devices has the ability to use J-Links with different USB ID and the ID can also be changed with J-Link Setup dialog.

J-Link Commander is a free command line utility for simple analysis of the target system with J-Link. J-Link Commander also allows downloads into flash memory of target systems.

How to perform downloading into flash via J-Link Commander: • Connect J-Link to the PC. • Connect target system to J-Link • Start J-Link Commander. • Type the following commands: J-Link> device // For a list of known devices, please refer to J-Link> r J-Link> h J-Link> loadbin, • J-Link Commander executes the flash download and prints out the time statistics on success.

Connect J-Link to the PC.Connect target system to J-LinkStart J-Link Commander.Type the following commands: J-Link> device // For a list of known devices, please refer to here J-Link> r J-Link> h J-Link> loadfile, J-Link Commander executes the flash download and prints out the time statistics on success. The flash download performance with J-Link has been tested with various devices. These tests were performed with J-Link Commander by placing an image of the full flash size of the device into the flash memory of the device.
