It is capable of running Go programs and sdk. The code is here as a drop in replacement for existing /sys/src/9/bcm: https://github.com/sirnewton01/rpi-9front Also, there is a release with an sdcard image there from the last 9front release. Tested briefly with a Pi B+ and Pi 2 B. In theory it could work with other models such as zero. If you find problems either with the code or in testing comments are welcome either as response to this email or github issue. Pull requests are welcome.

I = have released an experimental 9front raspberry pi image that I use for = my cluster.
https://github.com/sirnewton01/rpi-9front/releases/tag/nov-2016=

Highlights:
-Latest 9front release = 2016-10-27
-Merged in Richard Millar=E2=80=99s = kernel from a couple of months ago
-Retains 9front = GPIO filesystem structure
-Link local ipv4 address = on boot (low likelihood of collisions)
-Discovery = of other nodes using multicast DNS through the =E2=80=98find9p=E2=80=99 = command
-9fs mount other nodes on the = network
-Go 1.7.3
-Git script = (works with github and google source repos)

Cheers,
Chris

The implementation cam= e from what is in 9front mainline and is in #G. I agree that it would be goo= d to have a manual page for it there. mDNS is running as bcast9p process and is written in Go. It's based on a Go l= ibrary and uses udp multicast support for plan 9 that is only in latest git m= aster branch, slated for Go 1.8. Go SDK in this image is 1.7.3 though.

Interesting data point. Thank you. I tend to keep mine plugged into an activ= e Ethernet switch. I'll try without to see if I can narrow down the problem.= >=20 > I looked the source code and I guess for raspi 1: > Plan9 BCM pin > GPIO0 17 11 > GPIO1 18 12 > GPIO2 27 13 > GPIO3 22 15 > GPIO4 23 16 > GPIO5 24 18 > GPIO6 25 18 > GPIO7 4 7 > GPIO8 28 24 > GPIO9 29 21 > GPIO10 30 ? > GPIO11 31 ? > SDA 2 3 > SCL 3 5 > CE1 7 26 > CE0 8 24 > MISO 9 21 > MOSI 10 19 > SCLK 11 23 > TxD 14 8 > RxD 15 10 >=20 > and I tried some experiments. >=20 > (a) turn led light on/off that is connected to GPIO0 pin Cool, good to know that part is working for others. >=20 > term% echo function out GPIO0 >ctl > term% echo 1 > GPIO0 > term% echo 0 > GPIO0 > term%=20 >=20 > the result is OK. >=20 > (b) read GPIO1 status >=20 > term% echo function in GPIO1 >ctl >=20 > I expected: > term% cat GPIO1 # low voltage > 0 > term% >=20 > however I have: > term% cat GPIO1 # low voltage > 000000... >=20 > I expected: > term% cat GPIO1 # high voltage > 1 > term% >=20 > however I have: > term% cat GPIO1 > 111111... >=20 > is this a feature or bug? >=20 This part is inherited and merged in from original 9front source code. As we= discussed before there seems to be no manual page. I'm not sure the intende= d behaviour and I have not yet tried reading from a gpio pin myself. So in either case on the read it just repeats forever until interrupted? Chris=
