Pinephone and open source firmware for baseband

[justneedsomedatathanks]

What the posts by GrapheneOS complain about are that even in Biktorgj's modem firmware, the DSP firmware is still the same proprietary blob as in the completely proprietary firmware, and they claim that this is not properly communicated by Pine64. In the end, it all amounts to disagreeing on what "modem firmware" and/or "baseband firmware" really means (and whether they are the same thing or different things).  Biktorgj himself is pretty upfront on what his firmware replaces with Free Software and what not, in any case.

Thanks. As far as I can tell, there is no mention of this on the public pages of Pine64. You would have to search pretty hard to see this. This wiki page on the modem does not mention free software once, and says Pine64 also can't recommend alternative firmware: https://wiki.pine64.org/wiki/PineModems#...e_firmware

And then there's this line, which states, with no room for interpretation, you cannot replace the ADSP blob:

Further, there's no source for the OpenEmbedded parts, so building a new system image must be done from scratch, and retrieving the mandatory binary blobs to use the ADSP part of the modem.

(emphasis mine; Pine64 says the binary blobs are mandatory)

Seems pretty clear-cut to me. These claims from GrapheneOS are outdated at the very least and not a reason to say Pine64 is dishonest. I'll mark this thread as solved for now, but anyone else can chime in if you have more to add.

Thanks for contributing to the discussion, everyone!
