Signetix - Embedded Unix-like - NO GPL!!!
Signetik now provides an embedded Unix-like solution (Signetix). Signetix is designed for embedded systems requiring a more professional, close, secure alternative than Linux. It is tailored to ARM application processors, allowing for such features as UART, I2C, SPI, USB, Ethernet, WiFi, Audio, Video, and much more. Fast boot, robust filesystems, and IoT support, including robust system updates make Signetix an ideal solution for embedded designs that require Unix/Linux-like features, while avoiding many of the problems of these systems, including the GPL licensing problems.
