Sauraen Posted March 26, 2014 Report Share Posted March 26, 2014 Just started working with one of these for my job, and immediately started thinking about a possible port / extension of MIOS32! System: $45 1 GHz CPU with floating-point accelerator 512MB DDR3 RAM @ 800 MHz (plus CPU caches and RAM) 20M polygons/sec 3D graphics Two 200MHz 32-bit PRU processors with separate cache and RAM Included peripherals, all of the following supported simultaneously: USB Client (miniUSB to computer) USB Host (USB A to MIDI controller, etc.) Ethernet miniHDMI, up to 1080p @ 24fps Onboard 2GB eMMC (bootable) microSD card slot (bootable or data) 3 bidirectional UART (MIDI ports) plus one additional UART output only 1 SPI (DIN/DOUT) (there's two, but the other conflicts) 1 I2C (GM5, etc.) (there's two, but the other conflicts) ~20 free pins GPIO (SCS, software-based SPI for LCDs, parallel interface to SID, OPL3, etc.) I know one of the problems with Raspberry Pi was the lack of support for a FreeRTOS-based solution. For this board, there's a library from TI (free but probably closed-source) that includes USB and Ethernet drivers intended to work in a no-OS or RTOS environment: http://beagleboard.org/project/starterware/ Quote Link to comment Share on other sites More sharing options...
