WP76xx Linux without Legato

Just wondering, is it possible / has anybody used the WP76 modules without the Legato layer? We don’t need it, so it would be simpler not to have that extra layer of complexity and not have our software team learn a new framework, and would free up a bit of storage.

We would need:

  1. QMI (or ppp)
  2. GPS
  3. GPIO
  4. SD storage
  5. USB
  6. GPIO
  7. Audio

Has anybody done this, or are the services too integral with Legato?

Hi @sciscitatio, you can use the WP76 modems with PPP/AT/QMI interface to a host. The modem in this case will be just a bit pipe. You can also use it in ‘hybrid’ mode, bit-pipe with a host along with app(s) running on the the application core.

Thanks, yes we already did that, but I was more interested in the idea of removing unnecessary (to me) components from the build. I’m intending to use these modules in a commercial product so wanted to use a stripped-down OS build if at all possible. Our software guy assigned to this project has managed to set up a dev environment and compiled a fresh build using the Yocto tools but from what I can gather most if not all the documentation assumes a Legato build, so it’s not clear where dependencies lie.

We’ve done similar exercises on ARM SoC before, but nothing like these WP modules which seems to be a mix of open-source and proprietary.

Same here. Want to do a proper cross-compilation without using the developer studio/legato bollocks. Any ideas?

I wouldn’t hold your breath, this forum is about as lively as a snail on Valium.:sleeping:
