Last version of Segger Jlinksoftware issue with nRF52840 preview DK

[Fabien Comte]

Hello,

I updated Segger Jlink software to the last version and there is an issue with the nRF52840 preview DK.

Segger gives popup about updating firmware but it cannot success. Same issue with the last jlink firmware from Nordic website.

Output:

New firmware:  J-Link OB-SAM3U128-V2-NordicSemi compiled Jan 12 2018 16:05:20
Current firmware: J-Link OB-SAM3U128-V2-NordicSemi compiled Jul 24 2017 17:30:12
