i have loading driver modules for my wifi AP6212(BRCM43430),when i ifconfig wlan0 up and start up the hostapd service i can find the hotpot, but when i running a application  of video in and out to lcd with mcu of hisi3519v101, the hotpot will disappeared immediately. also i try to start up the application firstly and then to run hostapd, the log shows that the ap enabled,but i can't find hotpot neither. do some guys have the same exprience(my kernel is 3.18, and the wifi driver backports form 4.14.77, using brcm/brcmfmac43430-sdio.bin for chip 0x00a9a6(43430) rev 0x000001, Firmware version = wl0: May  2 2019 02:39:18 version 7.45.98.83 (r714225 CY) FWID 01-e539531f)?

the log is:

first: i run hostapd and then run the application ,

~ # ifconfig wlan0 192.168.1.1

IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

~ # hostapd -B /etc/wireless/hostapd.conf

Configuration file: /etc/wireless/hostapd.conf

wlan0: Could not connect to kernel driver

IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

wlan0: interface state UNINITIALIZED->ENABLED

wlan0: AP-ENABLED

here i can find the hotpot. then i run the application, the hotpot will disappear.

second: i run application and then run the hostapd,
