As I mentioned earlier, my backup plan is to use a J-Link device, It should show up in a day or two, and I am reasonably confident that will work.
I am impressed with the huge number of boards that Zephyr does support, kudos to the Zephyr Project for getting so much running. Hopefully the project team will have a chance to get the various debuggers cleanly integrated and make every board really easy for newbies….
We’d be happy to accept changes for the boards to support both w & w/o the bootloader. I haven’t looked at the submissions for the existing boards, but I’m guessing that for a number of boards the quickest way to get Zephyr going was to ignore the bootloader.
