I cannot connect my TM4C1294 lauchpad to the portal through Ethernet cable, it shows offline


I try to connect TM4C1294 launchpad to the exosite by Ethernet cable. The first time is working, but when I want to reconnect it to the exosite, it shows offline, and the LED D3 and D4 are not blinking. I checked power select jumper is in the “ICDI” postion.

Please help me solve this problem.
Thank you


Hi @zhouz,

Have you had a chance to look at the troubleshooting guide for the TM4C?

The first steps are typically validating that your device SN can be activated, whether or not the device has its CIK in memory, or if the device is connected to the internet.

Happy to help,
