Hello
The question has already been asked (at least here and here) but has been [ABANDONNED]...
I'm trying to connect to an MbientLab MetaMotionR device (actually a Nordic nRF52382) with SWD to flash and eventually for RTT.
Keil uVision can only see the device below 100kHz clock, above nothing appears (see pics 1 & 2).
When I try to connect with J-Link commander v6.54, same situation: works at 100 kHz (pic3) and doesn't above (pic4 & 5), with the error message mentioned in this message subject.
Finally, flashing from uVision (SWD at 1.5 MHz) works perfect with a ST-LINK v2 device.
Do you have any clue?
Thanks,
Sebastien
The setup has been working for several months and I didn't change any hardware.
