I have some copy jlink, they can used in keil and JFlash.exe, but can not use in nRFgoStudio.exe, is it right? nRFgoStudio can not support copy jlink edition?
We only support the official version of jlink. Using "copy jlink or not legal versions" would create issues that are unsupported and reduce your productivity, increase your cost and time in dealing with weird support issues. You must contact your manufacturer for any issues.
Edit added: I hope you are aware that the nRF51-DK and the nRF52-DK allow the onboard jlink emulator to be used to debug your custom board (nRF5x devices) over SWD, this provides a reasonable way to debug your custom boards without depending on "copy jlink".
