Not uploading to Redbear Nano BLE v2

PlatformIO IDE
1

On Mac OS X 12.1 with board redbear_blenano2, all of my attempts to use the board don’t do anything when it comes to interfacing with the physical board (but I don’t see errors) . I’ve tried the Arduino IDE/blinky apps and my board works fine, so I know it’s not a hardware issue. I’ve also tried zephyr/west direct installs and they work fine. So something seems to be amiss with my platform.io setup. Below is output for my upload command. Interestingly, platform.io is reporting to be using OpenOCD, whereas the direct zephyr/west cli is using pyocd which is reporting successful uploads, looks like a good hint the the issue? Advice welcome!

Both pyocd and openocd should be able to upload the program…

What does the project task “Advanced → Verbose Upload” say?

I seem to just get an extra line of info about using swd transport:

…OpenOCD really shouldn’t hang up like this. The invocation line seems perfectly fine.

I’m not sure whether its stuck because of some low-level USB failure or driver issue or because of something else. Please open an issue in GitHub - platformio/platform-nordicnrf52: Nordic nRF52: development platform for PlatformIO.
