I am working through the dev kit guide (section 4) and am getting error 8 when I update the mote firmware (hello_world) using ‘bridge dfu’. Node 4e768373dd4f80aa update status: 0, 8 Update finished: 4e768373dd4f80aa success: 0 err:8 I had the same error with the ‘v0.11.1_hello_world_RED.elf.dfu.b…

Hi John, sorry you’re having trouble. I assume your computer is connected with a USB cable to Spotter, not the dev kit. Correct? What’s the full bridge dfu command you’re issuing? What output do each of the following 3 Spotter commands give? bm topo bm info 0 ls Additionally the full console ou…

I am connected via USB to the Spotter, not the dev kit. bridge dfu bm_mote_v1.0-hello_world-dbg.elf.dfu.bin 0x4e768373dd4f80aa 200000 force ‘bm topo’ is not recognized as a command on the spotter. On the mote it gives: ‘(root)4e768373dd4f80aa:1 | 1:e6efd2fed740cfb9’ ‘bm info 0’ is not rec…

I see in your original comment that you’re trying to program recent firmware, v0.11.1. That version is incompatible with what your bridge is currently running, which is reported as v0.4.0 in the gist. As of v0.11.0 there was a breaking change with any versions before. You can learn more about that …

Hi @kucewicz – another option is that you weren’t waiting for Spotter’s 2 minute initialization window to complete before issuing the update. (see troubleshooting notes here: Notion – The all-in-one workspace for your notes, tasks, wikis, and databases. ). FYI – As of v0.11, it will no longer be req…

I did find that information about error 8 so was careful about giving it at least two minutes to initialize. I don’t think that’s the problem that I’m having, but I do have a question about the initialization. Unless it needs to reboot or some other unusual situation, does the initialization happen…

@kucewicz the initialization happens whenever the Bridge processor (essentially a Bristlemouth Mote inside of the Spotter) reboots. This will happen when Spotter powers on or resets, but there are a few other slim cases where the Bridge will reset independently. (Not having to worry about this const…

I have updated the bridge firmware, but now I am having problems updating the Spotter firmware. If it matters, I am running MacOS Monterey, version 12.6.5 on a Dual-Core Intel I7. When I run ‘spotter-flash-upload’, this is what the opened terminal shows. I have checked by running ‘pip list’ that py…

:man_facepalming: We just discovered this issue with the intel mac installer the other day. We’ve found and fixed the issue for future builds. I’ll post a fixed installer for v2.15.1 today or tomorrow and link to it from this topic. Sorry you got bit by that.

Glad to hear it’s not something stupid I’m doing on my end. If I have time today, I might go ahead and try it with the Windows installer.

I went through the process of updating the spotter and the bridge, but I think I did something wrong because I’m having a lot of problems right now. I’m wondering if I used the id of the spotter rather than the id of bridge when updating the bridge. If I understand ‘bridge test’ properly, it’s tell…
