i.MX6UL EVK with Murata ZP integration

[soumyaks]

Hi,

I am using Murata ZP BCM4339 module with i.MX6ULEVK kit. The BCM driver is provided along with the Linux 4.1.15 that i am using. 

I have used the Murata Users Guide and got the BCM module up and running on the image provided by them which is Linux version 3.14.

But on the Linux 4.1.15, i get the following error when I modprobe the driver.  

root@imx6ulevk:~# ifconfig wlan0 up

Dongle Host Driver, version 1.141.92 (r)

Compiled in drivers/net/wireless/bcmdhd

wl_android_wifi_on in

mmc0: queuing unknown CIS tuple 0x80 (2 bytes)

mmc0: queuing unknown CIS tuple 0x80 (7 bytes)

mmc0: 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

_dhdsdio_download_firmware: dongle image file download failed

dhd_net_bus_devreset: dhd_bus_devreset: -35

dhd_open : wl_android_wifi_on failed (-35)

wl_android_wifi_off in

dhd_prot_ioctl : bus is down. we have nothing to do

dhd_net_bus_devreset: dhd_bus_devreset: -35

ifconfig: SIOCSIFFLAGS: Operation not permitted

root@imx6ulevk:~#

The BUS down error is seen even when I take the BCMDHD firmware images from the 3.14 and load it in 4.1.15.

My dts looks like this:

&iomuxc {
imx6ul-evk-murata-v2 {
pinctrl_wifi: wifigrp {
fsl,pins = <
MX6UL_PAD_SNVS_TAMPER1__GPIO5_IO01 0x03029
>;
};
};

Can anyone please tell where I might be going wrong?

Many Thanks in advance,

Soumya

Hello Soumya,

   According to your logs, before loading dhd.ko, firmware files were not loaded correctly, so you can use insmod command to load driver module with parameters, like bellow:

# insmod /system/lib/dhd.ko "firmware_path=/system/etc/sdio-g-cdc-full11n-reclaim-roml-wme-idsup.bin nvram_path=/system/etc/nvram.txt"

   you can ajust your firmware path according to your system.

Have a great day,
(weidong)
