Niklas,
I bought J-Link edu several days ago and am now trying to
bring up it with i.MX6Ul board. But until today I always get message:
Cannot connect to target.
What I did:
-----------------------------------------------------------------------------------
- according to the link wiki.segger.com/IMX6UL-EVK,
I removed and assambled the mentioned resistors on i.MX6UL board
- according to the link wiki.segger.com/IMX_Series_Devices,
I set the device to MCIMX6G1
What I get:
