@SuperDicq @benthor @bitals @jae The pinenote contains a 802.11ac card that runs proprietary software and I figure the bluetooth card is integrated into the same chip, but requires another proprietary program.

The pinenote also uses LPDDR4 and the only systems I know that have free software DDR4 RAMinit are the Talos II ones.

e-ink waveforms can have software appended, but in many cases they don't and they may not even qualify for copyright, as a waveform is a mathematical table tailored for a specific screen (and only one table will do really) - although it'll be better if the waveform format was documented.

Manufacturers know this, which is why they demand a NDA is signed (to betray humanity by not sharing the waveform), before they'll provide the waveform needed to use the screen.
