I already has some experiences with Vortex86, we used at work this miniPC: http://www.asm.cz/zbozi/rb-262sxv2cf300mhz1x-lanfanless-minipci-2xcom.html Its was quite expansive that time, about 330$. I would call it 486SX on steroids. It even missing the FPU and standard debian kernel went panic :P After recompiling, I just don't remember that few kconfig options, then it worked. Does Vortex86EX have FPU?
That miniPC uses Vortex86SX, which is the first chip in Vortex86 series.
And the x86 Arduino project uses Vortex86EX, which is the sixth chip in
Vortex86 series. FPU has been added into Vortex86EX. Currently, Ubuntu
12.04 can directly be installed and run on Vortex86EX without kernel
modification.
> You say "we develop this year" - are you the Vortex architecture designer? Cool. I tried a bit of silicon chip design at school but now I work with available ICs and integrate them...
I am in the design team of Vortex86 SoC.
> Can you give some price guess for the board?
The x86 Arduino may be about 50US. (I don't guarantee this. I am an
engineer, not sales, so the board isn't priced by me.)
> You didn't mentioned the VGA - how about user interface? Is it only terminal via UART? How windows and DOS can handle it? When I saw the zero board with PCI-E connector it come in my mind that it could share some memory mapped framebuffer to host PC...
You can add a PCI-E VGA card to have Display. Terminal via UART is also
supported by BIOS. The Zero board's PCI-E connector is a PCI-E UART to
host PC (16550 compatible, but with 6Mbps and 128-byte FIFO).
> Also it would be nice to add legacy SoundBlaster/GUS/GMIDI support. If you can do it directly on chip or by external CPLD. Or just wrote SMM handler trapping legacy IO and transforming them to HDA output. AMD did it similar on their Geode CPUs (VSA). I have one machine With Geode 300MHz and sound really works there without any special driver but the board is crippled because missing PS/2 for KB, just USB and it uses obscure NAND flash disc...
We are developing a DJGPP HDA library for Vortex86EX. Compatibility to
legacy SB/GUS/GMIDI will be reserved to users.
> Good, I know one of CB developer, Rudolf... He already told me about biffer board but not about this project...
We just submitted codes to the coreboot team recently. They should have
known Vortex86EX last weeks.
> What about QEMU with HDD image+freedos+djgpp? For those we still sticked on 32b no problem run native...
We have tried QEMU (and other x86 emulators), but it is difficult (and
inefficient) to be integrated into the Arduino IDE. So we select DOSBOX
in the x86 Arduino project.
