PXA270 and it's framebuffer - 2700G OpenGL ES >"When you say boards with OGL ES graphics chips come with the drivers in them, do you mean the OGL ES driver is inside the graphics chip?" inside box.. on CD or floppy :-) ____________________________ you got right to the point there actually, drivers do belong in hardware, if you ask me... i just fail to see why not we already do have pixel/vertex shaders, which is, roughly speaking, a way to put software(drivers) into hardware.. but what scitech already did do, is that they "isolated" all platform and OS specifics out of the drivers (device code) so, we have: one device <-> one driver (+ os/platform specifics) AMD if wanted could put those Scitech binaries *inside* the chip and you would just get your +os/platform specific code on CD or floppy... the same thing is with OpenGL ES drivers, as long as something is "standard enough" drivers can be made easily to support multiple OS and architectures (separate device code from os/cpu code) the best thing with OpenGL ES is that - it came to be as no other standard before, in computer video industry as you know well, in windows and in linux nothing works without drivers... and if you look around the internet all the problems people EVER have is because of the drivers... > Help, my ______ is not working? my OS is _____ where in most cases soulution is just to go somewhere and download and install correct driver ...unless, of course, it is hardware fault or virus and these OpenGL ES drivers are just like SciTech *os/platform independent*, and as long as they are like that its fine - no real need to be inside the hardware... i do believe, however, they will soon start doing this... and as a matter of fact you might be right after all - its not impossible that OpenGL ES chip comes with some 'driver' inside http://www.compulab.co.il/x270/html/x270-cm-datasheet.htm But apparently $350 for one board. http://www.barnardmicrosystems.com/L3_avionics.htm ........... it looks to me that modifying bumstix to use OpenGL ES might be a matter of only purchasing OPTIONAL 2700G chip that somehow can be connected to that "LCD controller", that would be great howover, the only board that does offer that option right now seem to be one you found: CX-X270 http://www.compulab.co.il/x270/html/x270-cm-datasheet.htm i can not find any similar boards with nvidia/fujitsu/ati(amd) graphic chips, but i think soon there will be some, and all OpenGL ES boards are compatible within one OS, no matter if its x86 or ARM or other OpenGL ES seem to be very well supported by manufacturers - that means that bumstix, even as an ARM architecture is not a problem anymore.. at all! everythig is there - SDKs, development kits, 3D modeling software, 3d visualisation engines.. everything! so, i was wrong... there IS lots of people that DO compile for ARM and apperantly it all works rather smoothly! ah, buy the way... since ARM is popular platform it might be quite possible to have OpenGL *without* 2700G chip, i was only worried that we might not be able to compile stuff for ARM easily and i thought no one would ever bother to port mesa there... / "CRT controller" does seem to be doing the job of being "video chip", where it would be preferable to have one with as much framebuffer as possible (framebuffer = "VRAM" - video memory), only the memory that "LCD controllers" can utilize seem to be only 'normal' RAM (SDRAM) in New Zealand, no one seem to have ever even heard of anything like bumstix, the closes thing i can buy is DELL pda, full device with PXA270, but its$800 and doesnt have 2700G so i oredered one of these from australia, i hope ill have it in a week CX-X270 http://www.compulab.co.il/x270/html/x270-cm-datasheet.htm one of my goals now is to make Linux based OS that will work just the same if you boot it on PC, laptop, mobile phone or anywhere else where OpenGL can run - with universal embedded/desktop *3D windowing sytem* built with OpenGL, visualy similar to - Compiz/Beryl/Vista/MacosX the other thing id like to be able to do is - to make a board even SMALLER than bumstix only to have CPU-RAM + GPU-VRAM pairs on it ! and get rid of all serial/parallel, ac97, wi-fi, advanced PCMCIA, I/O, COM.. well anything but CPU+GPU and memory they need.. / i would instead put only few BUT much more Plug'n'Play' oriented connectors - like USBs for keyboard/mouse and also couple TV-out CRT/LCD connectors like on graphic card, so it would be easily pluggable just like any other PC.. its possible to connect pretty much any device to usb and it wouldnt require any additional accessories(there might be even more suitable connector for multy-purpose like that) i guess those pin based connectors that they use on bumstix are prefferable if you want to integrate parts tightly together and minimize the use of cables, but (all) connectores could be made two-sided, so that you could do both - connect externaly with cable and/or internaly with some pin/slot connector it looks like such *CPU+GPU only* combo could fit on 1/3 of bumstix i'll try to conntact AMD to see if that can be ordered (it looks like thats exactly what they offer, when they say - design your own board!), cost of that stripped board might be even less that $70, especially if oredered directly from AMD they dont mention if thats open for individuals/hobbists or only for companies that order large volumes.. i also sent e-mail to bomstix sales@ - to ask if they provide optional 2700G chip and if there are any price drops on volume orders, since there is nothing even close to that here in NZ, it seems i could make business just by importing bumstix and selling customized embedded solution kits or something like that, i guess i could also make my own Linux based mobile phone or PDA or Linux "GameBoy" or whatever : - ) cheers, p.s. did you get myOS running?

SciTech products support Linux (with or without X11), Qt/Embedded, Windows NT, Windows 9x, Windows CE, OS/2, On-Time RTOS 32, and DOS operating systems and now support x86, x86-64, Power PC, and MIPS (32 and 64bit) processors. ******************************************************************************************************** btw, this might prove useful, its the cheapest hardware store i know of.. ***************************************************************************** ***************************************************************************** 17'' laptop AMD Turion 64 ''$599 refurbished, in most cases they are all brand new! http://www.saveateagle.com/av7155ea1-ref-v14.html you might know about: http://www.saveateagle.com/ ***************************************************************************** *****************************************************************************
