DM385 USB with Wifi Interface not working on CBB RDK Kernel

KALPESH PANCHAL
Intellectual 265 points

Other Parts Discussed in Thread: DM385

Hi All,


We are using CBB RDK GA 1.3 for DM385 .

we need to interface USB based Wi-Fi and BT module.

We are able to enable USB Host interface on our custom board. So we can detect USB flash drive and USB SD card reader on USB port.

Now When we try to load Marvell's USB driver with CBB RDK Kernel we are getting Kernel crash as shown below.

USB Driver is able to load Wi-Fi firmware but then after Kernel crashes at "woal_submit_rx_urb".

Are we missing any  configuration in Kernel or filesystem ?

Steps:

# cp usb8766_uapsta.bin  /lib/firmware/mrvl/usb8766_uapsta.bin
# insmod mlan.ko
# insmod usb8797.ko 


Anyone knows the problem or possible solution??

It would be very much helpful for us to identify root cause.


Thanks in advance,

Kalpesh Panchal

    Thanks for your feedback,

    I found solution that we have to compile our kernel with option
    CONFIG_WIRELESS_EXT=y

    Now going foreword,

    We are able to load Wi-Fi Driver successfully and able to get device entry for mlan0 and scan SSID,
