How to start wifi ap mode using AP6212 by hostapd/wpa_supplicant?

[christsang]

Hi everyone, 

I am in the development in my custom board base on imx7dual sabre board, while the wifi module is replaced by AP6212. 

The STA mode works fine that it can connect to other access points. But for the Access Point mode, the ssid that I set never showed up. I tried using the hostapd or wpa_supplicant, but still got the same result. I have confirmed my device is work in AP mode, which is one of the supported modes.

Btw I also tried to do the following manually:

echo /lib/firmware/ap6212/fw_bcm43438a0_apsta.bin > /sys/module/bcmdhd/parameters/firmware_path
echo 2 > /sys/module/bcmdhd/parameters/op_mode
echo /lib/firmware/ap6212/nvram.txt > /sys/module/bcmdhd/parameters/nvram_path

but still get the same result.

The pre-built image for the imx7d sabre board does not have ap mode for the wifi. I have no clue at all.

# iw wlan0 info
Interface wlan0
ifindex 6
wdev 0x1
addr 44:2c:05:27:5c:4e
ssid test_device
type AP
wiphy 0
txpower 31.00 dBm

here is my wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
ap_scan=2
max_num_sta=5
network={
ssid="test_device"
frequency=2412
key_mgmt=NONE
mode=2

here is my hostapd.conf:

interface=wlan0
ctrl_interface=/var/run/hostapd
beacon_int=100
dtim_period=1
preamble=0
wps_state=2
eap_server=1
ssid=test_device
max_num_sta=5
channel=1
hw_mode=g

Hi Igor,
