other than a low-power, low-end pc, i wonder how
i could use this board.  it's relatively large and high
power for an embedded device (the chipset uses >
20w, and it doesn't have enough i/o to be a fileserver
or fileserver-like device.  it only has 10/100 eth
and no pcie.

I just saw a rumor today that it will have Atom soon.

AFAIK iPhone doesn't have an ia32 processor, so I don't see how you
can make 9vx work on it.

for info about inferno on the ds: http://code.google.com/p/inferno-ds/,
remember check the download tab for ready to run kernel images.
an excerpt from the README [1] about the status of the project:

	"The port [1] is starting to be usable,
	that means that limbo programs (dis code) runs on Inferno's Dis VM [2].

	Some of the hardware bits [3] that are working are:
	        - both lcd screens (including the touch).
	        - access to spi devices (arm7): touch, rtc, firmware, power, mic, ...
	        - mpu and caches are working.
	        - fifos for processor communication between arm7 and arm9.
	        - audio support (play and record).

	Still the port is far from finished, so the port is a WIP
	(work in progress) thing some of the bits missing are:
	        - sd card storage
	        - wifi networking"

Storage is working also, so the next big thing missing is wifi networking.

I'll back off filling the list. Contact me off-list if you wanna know
my experience with these devices.

Sorry Charles if I breached confidentiality - but that was pretty
accurate I think.

The core chips seem to be the same, but otherwise they're separate
projects AFAIK.

Back in the PC world, a motherboard w/ Intel's Atom chip can be had
for $80: http://www.newegg.com/Product/Product.aspx?Item=N82E16813121342.

Re: [9fans] Porting Plan 9 to the TI Beagle Board

[Pietro Gagliardi]

I'd like to see Plan 9 being run on a portable device, and up until
now I thought the only ways were to get an iPAQ (but are newer models
compatible?) or to port 9vx to the iPhone (but does Apple's license
allow that?). Can we use this board to make an alternative - the new
bitsy? This seems very feasible, since the board is only 3 inches long
(and I believe square). How would we get a three-button mouse to be
emulated?

Re: [9fans] Porting Plan 9 to the TI Beagle Board

[Bruce Ellis]

I've just discussed this with Charles. Vita has a thumb compiler (tc)
which works with 5l.

The Cortex-M3 is thumb-2 only so these two aren't quite sufficient,
but a flag will help.

the "fun" refers to this device:

[9fans] Porting Plan 9 to the TI Beagle Board

[John Barham]

In the recent NeXT thread Eric mentioned the TI Beagle Board
(http://beagleboard.org/).  It's quite neat:  $150 for a 3" x 3" PCB
w/ a 600 MHz ARM core, HD capable video, and SD card, audio, serial,
USB and DVI ports.  The documentation seems fairly complete, although
according the mailing list there are issues about how much of the
video and DSP interfaces will be documented.  Hardware-wise it seems
it only needs Ethernet to make it capable of being a Plan 9 terminal,
although in theory that can be added via USB.

How much would be involved in porting Plan 9 to it?  Would the current
Plan 9 ARM compiler be up to the task?
