Nanopi-neo, kernel: 3.4.112-sun8i, hostapd wont start

[mariusco]

Hi,

Board: nanopi neo, running xenial ubuntu server from:
http://www.armbian.com/donate/?f=Armbian_5.20_Nanopineo_Ubuntu_xenial_3.4.112.7z

 

I am trying to enable the hostapd for  nanopi neo, on

Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter

 

The default drivers

cocam@nanopineo:~$ lsmod
Module                  Size  Used by
rtl8192cu              61143  0
rtlwifi                45784  1 rtl8192cu
rtl8192c_common        33420  1 rtl8192cu
snd_usb_audio          80300  0
mac80211              358429  3 lrtlwifi,rtl8192c_common,rtl8192cu
 

came with 3.4.112-sun8i looks ok and my wlan0 is AP-advertised,

 

wlan0     Link encap:Ethernet  HWaddr ec:08:6b:1d:10:20  
          inet addr:10.5.5.1  Bcast:10.5.5.255  Mask:255.255.255.0
          inet6 addr: fe80::ee08:6bff:fe1d:1020/64 Scope:Link
 

As soon I connect a device to the AP I get a kernel crash:

I built against the /usr/src/linux-headers-3.4.112-sun8i kernel the rtl8192cu-fixes

and I blacklisted /etc/modprobe/blacklist.conf the old drivers, allowing the new driver.

 

blacklist rtl8192cu
#blacklist rtl8192c_common
#blacklist 8192cu
 

But now I cannot start the hostapd service

 

ifconfig

What can I try next. I am kind of stuck.

There are two versions of hostapd, hostapd and hostapd-realtek, both accessible from our repository ... try both, since it's try to match which goes where, and make sure you use proper config, check power supply that it gives 5V and not 4.7 or something, under load. Check following, tested but prepared for bridged mode.

For me , after compiling hostapd with go.sh

( note ; add pkg-config into dependances and i'm not sure that the deb was made , i made a copie hostapd* by hands)

it's the same

hostapd run with wlan5 , it began to talk and crash the machine just before dnsmasq

i have an extern power for a usb hub and make tests with 3 differents usb WIFI

 

i notice that for me driver=rtl871xdrv make an error

[gepeto]

in fact , it run :-)

my dnsmasq.conf and network/interfaces was wrong

then after all ( may be the apt-get update/upgrade are also important ) with driver=nl80211 it's ok

I have a captiv portal with nginx/php/dokuwiki to share information, data, etc   where i want  for 12$ .. cool

I 'll put documentation for that next week

I can't succeed with "NanoPi Air" Armbian_5.24_Nanopiair_Debian_jessie_3.4.113)

Hostpapd starts but I have no wifi, iwconfig show empty ESSID !

I tried go.sh but it tells me that some packages are held, event if I found nothing when "dpkg --get-selections | grep hold"

Chip is an AP6212 on my board, so I use hostapd (I tested hostapd-realtek one time)

Chip is an AP6212 on my board

 

...which needs dhd driver to be loaded with 'op_mode=2' to enter AP mode. You may create a file /etc/modprobe.d/dhd.conf with the following contents:

options dhd op_mode=2

Yes "It works" Haha !!!

I did not see anything with lsmod..... and tried to add wrong things in /etc/modules

Thank you master

 

The next step for me will be to switch between AccesPoint and Default connection

(I think I will need to reload kernel modules)
