J-Link do not recognize manufacturer.

[J.Kwon]

I debugged with pca10028, but J-Link can not recognize manufacturer.

If selected cortex-M0, it works but is very inconvenient.

How can I solve this problem?

SEGGER J-Link recognizes manufacturer automatically? You should select Nordic Semi in the first box and then you select your target chip. If you have full license to SEGGER tools then you can typically create projects with that information pre-selected and save time when opening.

Have you installed MDK package from nordic website?

I think it was automatically selected before.
