Correct, the version of openocd in homebrew does not work with nRF52. There used to be a link to pre-built binaries that do work, but that link is gone in the latest version of the docs. I have just run into this myself - no idea why/when the docs were changed.
Compare: http://mynewt.apache.org/v1_4_0/get_started/native_install/cross_tools.html#installing-openocd-on-mac-os http://mynewt.apache.org/latest/get_started/native_install/cross_tools.html#installing-openocd-on-mac-os There is still a comment about this in the new docs (in the previous section), but the link to download is gone and the instructions tell you to install from brew, which does not work. simon On Thu, Jan 3, 2019 at 8:09 AM Fabio Utzig <[email protected]> wrote: > Hi Duane, > > I believe, but am not entirely sure, that OpenOCD 0.10.0 release was not > able to flash nrf52x devices.
