Hello Craig!
you're proper cool ! Do you anything of your works public already?
is it possibly this? https://github.com/craigcomstock/osmocom-bb/tree/mt62xx https://osmocom.org/projects/cellular-infrastructure/wiki/Accelerate3g5_--_e...
I thought about MTK chipsets as good start-point for development, because they are less locked-down and there is bigger chance, they did not protect ie. the DSP codes enough.
Also the dev-board (mtk6260/fernvale) what do you use specifically?
Last thing, what I'm curious about, if Librem 5 (the phone) is willing to allocate some funds into BB(P) development and open-sourcing, because they sure want to open the software/firmware/hardware at some point, but so far I think, they rely more on BBP vendor to allow this, not so much opening it up / developing them-selves.
Cheers Marek

I am currently working on porting osmocom-bb to mtk6260/fernvale board available via open hardware and from sysmocom. My goal is to get a nuttx-bb + layer1 + mobile (osmocom-bb host software) working on fernvale and sim800h modules.
I am also working on integrating the old mt6235 sciphone g2 code as well as look dforward to 3g/lte with mtk6735as in the ZTE Obsidian.
I have some dreamy ideas about how to use fernly as a base for interactive creation and validation of board support and translate that into osmocom-bb firmware, nuttx application or library or even as a linux kernel driver or user space program (maybe in the ec20 qualcomm module case).
I'm not very far along but will try and share as many small PRs as possible . I would encourage others to do the same.
Cheers, Craig
