Glasnost M9G10 - Open Hardware Linux SBC

An open hardware and software Single Board Computer based on the Microchip AT91SAM9G10, designed for IoT and embedded applications with full SPI/UART/I2C expansion capabilities. This is a learning project exploring Linux board design with mainline kernel support.

Common interfaces such as I2C, SPI, UART and GPIO are exposed on the header.

⚠️ Boot Note


  
Unlike other Glasnost boards, this SBC does not include NOR Flash for a recovery environment. The AT91SAM9G10's limited peripheral availability means the board relies entirely on microSD card boot. Linux must be booted from the microSD card—there is no fallback recovery distro on internal flash.
