Specs:
Board: i.MX7D SABRESD RevA
CPU: Freescale i.MX7D rev1.2 at 792 MHz
Brcm chip: 43455 (SDIO)
Firmware: brcm/brcmfmac43455-sdio.bin
Kernel + FMAC used: https://community.cypress.com/docs/DOC-15932
I am trying to put the drivers into APSTA mode, where the board can connect to an upstream AP and can allow clients to connect downstream.
I have verified that drivers can be placed into STA mode, by configuring them for STA and connecting to a WPA2-PSK SSID and passing ping traffic.
I have tried running the drivers in AP mode, but have failed. I have configured the driver to broadcast an SSID on a particular channel, and have even associated a client to that SSID, but failed to pass any ping traffic. The linux wlan0 interface is up but not RUNNING, when driver is in AP mode. The wl commands for configuring in AP mode are below.
ifconfig wlan0
ifconfig wlan0 up
wl -i wlan0 down
wl -i wlan0 ap 1
wl -i wlan0 country US
wl -i wlan0 5g_rate auto
wl -i wlan0 bw_cap 5g 0x7
wl -i wlan0 ssid "001_mesh_open"
wl -i wlan0 bss 1
wl -i wlan0 chanspec 36/20
wl -i wlan0 txchain 7
wl -i wlan0 rxchain 7
wl -i wlan0 up
wl -i wlan0 bss 1
wl -i wlan0 status
wl -i wlan0 msglevel + assoc + error + info
ifconfig wlan0 up
What am I missing? Does the driver need to be compiled differently? Does the above firmware support AP/STA mode simultaneously?
Any help is greatly appreciated.

Could you check whether you are running a dhcp client in your STA. The problem might be that you are not assigned an IP yourself to begin with before pinging the AP.

Hi VinayakS_26,
Thanks for writing back. I just want to clarify that the issue with placing the drivers into APSTA mode. I have already placed the board in STA mode and associated it to an AP, but for the second step, I am trying to configure the board as an APSTA so that it can connect to an upstream AP as a client and clients can connect to it downstream.
What are the configurations required to place the board into APSTA mode?
EDIT: Also, it's not an IP address issue. When configured as a STA, the board is able to get an IP address with udhcpc running.
