Hi,
We have backported the latest compat wireless package (compat-wireless-2012-08-26) to Linux 2.6.28.2 kernel running on LPC3130 platform.
The firmware version used - Rev 6.3.10.2.115
Wpa Supplicant ver -1.0
We need to operate the wl1271 in concurrent mode.
The supplicant configuration is as follows
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
driver_param=use_p2p_group_interface=1
device_name=TI-WILINK-P2P
device_type=1-0050F204-1
#sec_device_type=1-0050F204-1
# If you need to modify the group owner intent, 0-15, the higher
# number indicates preference to become the GO
p2p_go_intent=15
# optional, can be useful for monitoring, forces
# wpa_supplicant to use only channel 1 rather than
# 1, 6 and 11:
p2p_listen_reg_class=81
p2p_listen_channel=1
p2p_oper_reg_class=81
p2p_oper_channel=1
network={
mode=3
disabled=2
ssid="DIRECT-AB"
key_mgmt=WPA-PSK
proto=RSN
pairwise=CCMP
group=CCMP TKIP
psk="12345678"
}
#####
I am starting the supplicant with the following command
./wpa_supplicant -Dnl80211 -i wlan0 -c /wlan/wpa_supplicant.conf -d &
Starting the supplicant is successful.
However, while making the device in Persistent Group Owner mode using the command( ./wpa_cli -i wlan0 p2p_group_add persistent=0), the driver crashes
The log as follows
/wlan # rz[J
/wlan # ls -l[J
/wlan # clear[J
/wlan # dmesg -c[J
/wlan # clear[J
