[9fans] my ts7200 port

found what is likely the latest version lying on my laptop from over
two years ago and dumped it in
sources in ts7200.tar

I got excited by the beagleboard again ...

Thank you for remembering to find this, it will be of great help to me!

which board/cpu are you targeting? I really like that beagleboard.

The TS-7200 Technologic board, the exact board in your port, I
believe.  The intent is to use it to netboot other machines.

Also of interest is the Technologic TS-7500,

http://www.embeddedarm.com/products/board-detail.php?product=TS-7500

for a wifi point that can serve a HDD, and also wake up an attached
larger machine and then attach itself as a usb device.  (The machine
has slave usb in addition to the host usb.)

Thank you for the Beagleboard information.  I have a need for driving
a small vga lcd with a low-power arm board.  The intent is to replace
my ailing terminal, a thinkpad 600e.  I had previously assumed the
latest Gumstix board would serve this purpose, I believe which is more
expensive.

OK, be warned, the ether driver in that tree is not very good. I just
ported the linux driver over and then ran out of time to do much more.

I'm interested in how hard this is, and how it might be made easier.

that depends.  i've found that porting a driver or working backwards
from an example is often harder than just writing a new driver.
this is because the hard part is understanding how the hardware works,
not in coding that knowledge up.  and unfortunately, looking at a
linux driver hasn't been very instructive to me.

i'm sure one could create a compatability layer for certain driver types
along the lines of ndiswrapper.  but given the instability of linux
internal interfaces, this might be finished about the same time as
duke nukem forever.

What about emulating a usb-ethernet device in software? (Assuming the beagle board's usb interface can operate in gadget mode as opposed to host mode.) The Linux kernel does a good job of emulating a usb ethernet device, I use it extensively. I rather assumed the Bitsy port had this already, but perhaps not.

The Linux kernel does a good job of emulating a usb ethernet device, I use it extensively. I rather assumed the Bitsy port had this already, but perhaps not.

Huh, I just realised that if both ends of the fake ethernet link run Plan 9 then the only advantage of what I suggested would be that both ends of the link are known quantities with open source code.

Now I wonder if it might be simpler to implement 9p directly over USB.

sure.

but you still have to solve the problem of talking to the usb device.

I'm curious....  When I first heard about the BeagleBoard a couple of
years ago, my first thought was, "terminal."  However, then I heard
that there was no builtin ethernet and one had to use a USB<->Ethernet
bridge.  This seemed unsatisfactory to me, but was in keeping with the
spirit of what the BeagleBoard folks were trying to do; has this been
rectified?  Is there now an onboard Ethernet device?  Or is the driver
in question for a USB ethernet thingy?

the object of the game is price and power.  Performance doesn't
factor, notwithstanding that the terminal must drive 1024x768 vga.

unfortunately x86 cannot be beat, if the object of the game is price/performance.
i'm trying to work out the details on a non-intel fanless atom system.  it
appears that everything works well on this system; dual-ethernet, serial,
sata, ata, usb.  i haven't yet tried the on-board vga.  it looks to be in the
price range of the fancier gumstix motherboards.
