i.MX6 wifi driver can't working

[sunnyhyh]

Hi all,

Recently,I have a problem when using USI wm-bm-bn-04-a(it's same asBCM4330) wifi module on a i.MX6 board(NITROGEN6x) with Android 5.1. In addition ,linux kernel is 3.14.52.

Here is part of the dmesg:

Please help me analyze it and give some advice. Thanks!

Hi,

Can you confirm that you've added this WiFi module yourself to the board?

We only offer the Nitrogen6x with a few supported WiFi module and the USI wm-bm-bn-04 isn't one of them.

In that case, please make sure you've done all the porting job and not just using our standard release. Also check the firmware files, it most likely need a custom NVRAM (new routing).

Regards,

Gary

Hi，Gary

Thank you for your reply!

I don't know whether Nitrogen6x support USI wm-bm-bn-04-a wifi module?Hardware has been decided, I can only try to do it.

By the way,the firmware and NVRAM files are "brcmfmac4330-sdio.bin" and "brcmfmac4330-sdio.txt".

About DTS:

Most BCM configuration is in "imx6dq-sabresd.dtsi", but I should add some configuration in "imx6qdl-nitrogen6x.dtsi".

Hardware pin configuration is as follows：

SDIO_HOST_WAKE <->MX6QDL_PAD_ENET_TXD1_GPIO1_IO29

WL_REG_ON <->MX6QDL_PAD_ENET_RXD0_GPIO1_IO27

WL_WAKE<->MX6QDL_PAD_ENET_TXD0_GPIO1_IO30

How do I make changes according to the above in the "imx6qdl-nitrogen6x.dtsi"?

Can you give me some suggestion.

Looking forward to your reply!

Best wishes!

Hi,

Well in that case I'm afraid I can't help you since it's a custom design which I have no knowledge of (module schematics/mapping).

As a FYI, we've used the murata module (bcm43340 chip) with no modification in the past.

Regards,

Gary

Hi,

Um, I see. Thank you all the same.

Merry Christmas!
