Implementation of "Wi-Fi Access Point" on IMX7

vikram_bidkar — Fri, 07 Jul 2017 06:52:03 GMT

Dear All,

I am trying to implement "Wi-Fi Access Point" on the IMX7 evaluation board having Murata Wi-Fi chip(LBEH5HMZPC).

Below are my changes in .config file.

CONFIG_BCMDHD_FW_PATH="/lib/firmware/bcm/ZP_BCM4339/fw_bcmdhd_apsta.bin"
CONFIG_BCMDHD_NVRAM_PATH="/lib/firmware/bcm/ZP_BCM4339/bcmdhd.ZP.SDIO.cal"

CONFIG_HOSTAP=y
CONFIG_HOSTAP_FIRMWARE=y

but when I do "ifconfig wlan0 up" I am getting following error

root@imx7dsabresd:~# ifconfig wlan0 up

Dongle Host Driver, version 1.141.92 (r)
Compiled in drivers/net/wireless/bcmdhd
wl_android_wifi_on in
mmc1: queuing unknown CIS tuple 0x80 (2 bytes)
mmc1: queuing unknown CIS tuple 0x80 (7 bytes)
mmc1: queuing unknown CIS tuple 0x80 (6 bytes)
F1 signature OK, socitype:0x1 chip:0x4339 rev:0x1 pkg:0x0
DHD: dongle ram size is set to 786432(orig 786432) at 0x180000
dhd_bus_init: enable 0x06, ready 0x06 (waited 0us)
dhd_bus_rxctl: resumed on timeout, INT status=0x208000C0
dhd_bus_rxctl: rxcnt_timeout=1, rxlen=0
dhd_check_hang: Event HANG send up due to re=1 te=0 e=-110 s=2
dhd_open : wl_android_wifi_on failed (-14)

What could be the issue?

Note: Wi-Fi is working fine in client mode. It can able to scan and all.

Hi Vikram

please refer to additional documentation (probably you will have to ask access to it

using murata support portal : wireless.murata.com/eng/products/rf-modules-1/wi-fi-bluetooth-for-freescale-i-mx.html)

Thank you very much igor.

Sorry for the late response.

"Murata i.MX Linux 4.1.15_2.0.0" Quick Start Binary Patch Release does not contain bcm firmware file. It has only NVRAM file(bcmdhd.1CK.OOB.cal and bcmdhd.1CK.SDIO.cal ). Please let me know where can I get the proper bcm firmware file for Wi-Fi chip LBEH5HMZPC ( Access Point mode).

Thanks and regards,

Vikram
