That is wishful thinking. Try "adapter_khz 500" first.

That shows us nothing.

OpenOCD problems should be debugged with the "-d3" option enabled - that will produce MUCH more output. Some of it might be helpful even.

That seems unusually old. The OpenOCD 0.10.0 release date was in January 2017.

And I think there are some patches for NRF stuff later in git master - you might want to compile a more current OpenOCD yourself.

i think the latest version of OpenOCD is 0.10.0
