True++ there are at least 4-5 OSes on Qualcomm with direct access to the Internet:
1. Linux Kernel / Android OS, running on main ARM CPU in "normal mode"
2. QSEE or Trustonic OS, running on main ARM CPU in "trusted execution environment" mode, in parallel with "normal mode"
3. OKL4 / REX Kernel + AMSS OS, running on the baseband CPU (modem)
4. SIM card processor, although it is very limited (typically 32k RAM) and acts only as a MITM for SMS's, not cellular data
5. The OS running on the Wi-Fi card

- jkepler 8y agoDoes anyone know of any smartphone projects where the circuits are designed to give the user's OS (usually GNU/Linux, but could be anything the user fancies if the bootloader's free) control over power to the baseband CPU, SIM card processor, and OS on the Wifi card? As far as I know, the Neo900 project is the only one attempting to allow the user's OS to control power to all those other ones.
- fake-name 8y agoIt doesn't exist. And in the current market, it can't exist. All the core silicon is wrapped up in huge quantities of NDAs and licensing agreements. You buy a baseband, and the mfg gives you a blob you can either use, or not use the baseband.
