I’v been using Zephyr for about a year and I’m comfortable with updating devices with mcumgr over serial and bluetooth. I ship apps with Zephyr.
I’ve been itching to try out the 9160 that I snapped up in the first groupgets round, and I have just the project for it, but I just cannot get the 9160 feather to successfully complete an image upload. I should be using the newtmgr binary from here right?
Most often it dies uploading blinky at 97.3% (which would be about on the 64k mark, is that relevant?), but sometimes it dies around 10 or 20% complete.
I’ve never had a successful upload.
I’ve completely blown away and reinstalled my SDK following the instructions (I’m on nfed rev e8e4ddbba65ad055513d1cf8a76d573569337e94).
I’ve tried this on my Macbook (where I do all my zephyr coding, and on two different linux PCs). I’ve tried many different USB cables.
I don’t have a TagConnect cable, though I have several j-link and st-link boards programmers, and not afraid of jury-rigging a programming cable.
Can anyone suggest what I should try next? (Yeah, I’ll order a tag-connect cable, but I’m in Australia and there’s a huge inbound cargo backlog)
Grateful for your suggestions, –chris
