Cannot flash FRDM-KW41Z

When trying to add a new program, connectivity test as shown in the video getting started, I receive the following error and cannot figure out why. I have tried updating Segger with 24_OpenSDA_FRDM-KW41Z but except for the fact that the board that I tried that on now just shows a red LED glowing at J24 I have the same error. Did connect terminals to reset OpenSDA position.

Before using the KW41Z board I did some experimenting with the FRDM-KL03Z board since new to ARM and that worked out perfectly ok.

Hi,

I got the exact same error. Did you manage to recover the board ?
