I've seen 9 running on a raspberry pi, and now am really interested in buying a model A to run it on (maybe B to have some fun with 9P). But before I jump the gun, are there any known brick walls associated with this set up? Like needing two usb instead of a hub? Thanks!

I've started trying this this week, and it works, but I get a lot of USB
errors from my keyboard. However so far the keyboard works.

I haven't had time to do much beyond "ooh, it boots".

I have little plan 9 experience and was up and running in maybe 10
minutes using Richard Miller's image. No speed bumps, let alone walls.

Tried this, seems to eliminate the runtime console errors, but I still
get a "Report type 0x13 bad" at boot time.

An alternative to using a USB hub is to use a wireless keyboard/mouse
combo, I use the standard Microsoft one and it works well.

I'm very happy with Miller's port, it's the easiest way to try plan9 on
real hardware. I'm planning to port my Go program to Go on plan9
on the pi.

I also have a lot of USB errors with the keyboard connected to a
powered hub (missing some key events because the errors), but
it works plugging it directly to the rpi. Maybe ultracheap keyboard's
fault.

I use a Pi as my main terminal and find it generally works
great. I had a bunch of USB issues until I made sure I was
using a 10W USB adaptor and a powered hub.

In the round after mine, they made some revisions to the
power handling which I understand make it a bit less fussy.

Plan 9 works just as well on the model A as on the model B, except for
some problems with low-speed usb devices connected directly to the pi.
If you use a hub it should be fine.

Re: [9fans] Raspberry 9

Ah, wireless keyboard/mouse combo? That sounds much cooler. Any known problems? And does the wifi dongle newmark supplies work?

I've finally found the cause of this and supplied a patch to fix it.
If you pull and build a new bcm kernel, it should now work the same
on models A and B, with or without a usb hub.

I believe the model A pi is now in stock in the US too, so the long
standing "$25 computer" claim is now actually true.  Caveat: it's
for niche applications only - if you need to add an external
ethernet dongle or a hub to support more usb devices, it would
be cheaper just to get a model B instead.

where do you find the current plan9 image with the usb fix?

Which usb fix in particular are you referring to?

Sorry, I get this list by email so I don't always keep track
of intermittent threads.  I had forgotten my message under
this subject line three weeks ago, about sorting out usb for the
raspberry pi model A.

I've just put a complete new SD fossil image in the usual place
(/n/sources/contrib/miller/9pi.img.gz) with the model A usb patch
applied, and also updated for the new 21-bit runes.
