So you said you “read his code” because there was no documentation. Where are you finding all the code? Are you referring to the code in topikachu/python-ev3/ev3 directory? where do you find all the code on the EV3?

Thanks?

We merged Python 2.7 into the leJOS sd card image and use a TCP/IP gateway between Python and leJOS. For more information consult http://www.aplu.ch

sorry for the typo 😉

load driver:
insmod /lib/modules/2.6.33-rc4/kernel/drivers/net/wireless/8192cu.ko

Stas,
I figured out how to add 8192cu support on this image:

You can get the driver from here: http://www.electrictea.co.uk/rpi/8192cu.tar.gz

install the driver:
cp 8192cu.ko /lib/modules/2.6.33-rc4/kernel/drivers/net/wireless/

load driver on system startup:
echo 8192cu >> /etc/modules
depmod -a

load driver:
insmod /lib/modules/2.6.33-rc4/kernel/drivers/net/wireless/cp 8192cu.ko

ctrl_interface=/var/run/wpa_supplicant
network={
ssid=”your_wlan_ssid”
key_mgmt=WPA-PSK
psk=”your_wlan_presharedkey”
}

auto lo
iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp
hwaddress ether xx:xx:xx:xx:xx:xx #hardware address ev3

auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant.conf

reboot or /etc/init.d/networking restart

it should get an ip address now, if not check your settings and the /var/log/syslog

good luck!
Alan

And I’ve used topikachu’s branch rather than hmml’s.

Prebuilt image is not working for me as well, I’ve built it myself as described in here https://github.com/hmml/python-ev3/tree/refactor/build-rootfs
It boots now, but another problem arised: motors are not working

Stas, have you got 8192cu working in your side? I am going to give a try for this small wifi dongle. Would be good to know your progress if any.

The display kept showing that initial “mindstorms – starting…” message. It got stuck like that for over 10 hours. I was about to give up (I just cloned the ev3sources source code and was experimenting with sending C++ code via Bluetooth), but I’ll try reflashing the card, as you suggested.

Thanks for the help, Cecilie!
