Hello David: We met at the openiot summit in Portland. I decided to go ahead and re-flash the nano2 we have here and I did not have an issue with it. I know; that does not help. :-) I am running what I believe is close to the same openocd version as you are but an earlier version of osx.
If you have your board with you, bring it over to the booth and maybe we can help download it or at least try to debug what is going wrong. Thanks. > On Feb 22, 2017, at 1:31 PM, david zuhn <[email protected]> wrote: > > Having just received my Nano2 device, I'm trying to get the basic blinky > application installed.
