I don't strictly need a full Linux OS, but I have to use a third-party SDK released only for this OS (it is a commercial TTS engine solution).
What is the minimal hw platform that runs a full Linux (not uClinux)? Is there a single-chip (integrated Flash and RAM) solution? I don't think. What is the simplest and lowes cost solution for a medium volume production (1000pcs)?
I don't need TCP/IP, USB, Ethernet, WiFi, Filesystems and so on.
I'm not sure, but I think the TTS library doesn't use Linux services,, but only C library call. How do I understand which function calls are present in the pre-compiled library included in SDK?
If the library doesn't use specific Linux services, is it possible to convert a pre-compiled library for ARM Linux to a pre-compiled library for a bare-metal (no OS) ARM hw platform? Of course, the same ARM core.
