AP mode failed on wandboard with brcm4329 chip

Postby varkab » Wed Mar 25, 2015 8:37 am


I am trying setup wandboard-quad as Access Point. It has BRCM4329 WiFi chip on it.

As a client its working fine, but facing problem as a AP

I did following steps...

1. Linux kernel Configuration: Linux-3.19

i. Device Drivers > Network device support > Wireless LAN
Code: Select all
<M>  Broadcom IEEE802.11n embedded FullMAC WLAN driver
[*]  SDIO bus interface support for FullMAC driver
[ ]  USB bus interface support for FullMAC driver
[ ]  PCIE bus interface support for FullMAC driver
[ ]  Broadcom device tracing
[*]  Broadcom driver debug functions
<*>  IEEE 802.11 for Host AP (Prism2/2.5/3 and WEP/TKIP/CCMP)
[*]  Support downloading firmware images with Host AP driver                                 
[*]  Support for non-volatile firmware download                                             
< >  Host AP driver for Prism2/2.5/3 in PLX9052 PCI adaptors
< >  Host AP driver for Prism2.5 PCI adaptors 

ii. Networking support > Wireless
Code: Select all
<M>  cfg80211 - wireless configuration API
[*]  nl80211 testmode command 
[*]  enable developer warnings
[ ]  cfg80211 regulatory debugging
[ ]  cfg80211 certification onus
[ ]  enable powersave by default
[ ]  cfg80211 DebugFS entries
[ ]  use statically compiled regulatory rules database
[ ] cfg80211 wireless extensions compatibility
[*]  lib80211 debugging messages
< >  Generic IEEE 802.11 Networking Stack (mac80211)

2. Copied brcm4329 firmware and nvram txt file into lib/firmware/brcm/

3. hostapd.conf

Code: Select all
wpa_pairwise=CCMP TKIP

4. After booting into the wandboard, did the following operations

$ modprobe brcmfmac

$ dmesg
Code: Select all

Anyone made wandboard-quad as Access Point...? Am i missing anything...?

Hi guys,

I have Wandboard Quad C1 revision in hand and tries to configure it as an access point. I am But no success so far. I came across with this topic. I am currently using Linux Kernel 3.10.17 (Debian Jessie). Also, have brcmfmac4329-sdio.bin and brcmfmac4330-sdio.bin dated as 11/15/2013.

So, I just wonder if there is any update? Has any one achieved to get the access point running on WB Quad?

Thanks in advance.
