RayeR, there is under-construction website for this project (currently
only include pictures of the hardware and no more information):
http://www.86duino.com/index.php/products/
The x86 Arduino project is open source. We plan to apply a github page
and release all schematics and source codes of hardware and software in
the next month.
Its CPU is called Vortex86EX, a new x86 SoC that we develop this year.
The CPU runs at 300~400MHz and supports up to 1GB DDR3 DRAM. When
running at 300MHz, its speed is nearly equivalent to Pentium 233. Most
usual I/O are included in this CPU as ISA or PCI/PCI-E devices,
including PWM, I2C, SPI, UART, CAN, USB, LAN, HD Audio, SATA, SD card
(simulated as the standard IDE interface), ...
DOS, Windows XP and Ubuntu/Debian can run on this CPU.
The BIOS is developed by us based on coreboot and SeaBIOS, and will also
be open source.
The OS of the x86 Arduino is FreeDOS and is installed on the on-board
SPI flash (simulated as a floppy). The compiler for the x86 Arduino is
DJGPP, currently integrated in the Arduino IDE with the help of DOSBOX.
The first step for this project has been completed (i.e., the porting of
the original Arduino software/firmware), and we are working on the
second step to solve the 8.3 filename limit, to add the Ethernet and HD
Audio support in DOS, and to port Arduino's 3D printer and CNC firmware
on the x86 Arduino.
