I have a J-Link that I've used successfully for years over USB. I recently used J-Link Configurator to assign it an IP address and can no longer communicate with the device, either through USB or IP.
Configuration:
I have also re-installed the V4.84 J-Link software and rebooted the PC, all with no effect.
Configuration:
- Hardware: J-Link ARM Pro, version 3.0
- Software: J-Link ARM V4.84
- Environment: Windows 7
- Plugged J-Link into a USB port on my PC
- Ran Configurator
- J-Link was detected by Configurator
- J-Link firmware was updated to the latest revision
- Right-clicked on USB emulator, selected 'Configure'
- In the 'Configure J-Link' dialog:
- Selected Manual IP configuration
- Entered IP address, subnet mask, and gateway
- Clicked OK
- A dialog appeared stating "J-Link successfully configured. Please unplug and reconnect the J-Link before pressing OK."
- Unplugged USB cable from J-Link
- Plugged USB cable back into J-Link
- Clicked OK
- There is no evidence of J-Link in Windows Device Manager
- The middle (of three) J-Link LEDs is solid green regardless of whether target is powered or not
- Cannot 'ping' J-Link
- Cannot bring up J-Link web page in browser
- The middle (of three) J-Link LEDs is solid green regardless of whether target is powered or not
- Configurator cannot see J-Link over IP
I have also re-installed the V4.84 J-Link software and rebooted the PC, all with no effect.
