NRF52DK (PCA10040) cannot connect J-Link SWD at speeds higher than 1000 kHz

[bds]

My NRF52DK (PCA10040) J-Link always shows SWD speed 1000 kHz, even if I set the speed to 2000 or 4000 kHz. Is it not possible to connect at higher speeds?

Hi, I apologize for the late reply,

The speed is capped by the J-Link on-board debug probe found on the development kit. I am not aware of a method of checking what this cap is, but it seems to be 1000 kHz in this case. This is not lower than expected.
