You're forgetting the proprietary software running within the CPU bootrom, the LTE modem and other chips :)
Even if you are using the libre modem distribution, it only covers the ARM cores of the modem, not the Hexagon ones.
- seabass-labrax 4y agoThanks; I didn't know that! Do you happen to know whether Hexagon is just a simple DSP processor on the PinePhone's A64, or is more advanced with direct memory access etc.?
- pabs3 4y agoI think the Hexagon runs an RTOS of some kind. It is not part of the PinePhone SoC, but is part of the modem SoC (which has Hexagon cores and ARM cores), which IIRC is soldered onto the PinePhone board separately to the main processor SoC. https://en.wikipedia.org/wiki/Qualcomm_Hexagon https://en.wikipedia.org/wiki/Qualcomm_Hexagon
