broadcom wifi bcm4329 integration on imx6 target board issue.

[veeranjaneyulug]

Hi ,

we used kernel version 3.14.28 .we compiled broad com bcm4329 module out side of kernel, and generated bcm_dhd.ko,and we copied fw.bin and nvram.txt files into /lib/modules and /lib/firmware path .

3.14.28 kernel is support? for bcm 4329 module.we got below error.can you anybody help me.

insmod bcmdhd.ko firmware_path=fw_bcmdhd.bin nvram_path=nvram.txt iface_name=wlan

we inserted above all those things.

root@imx6qsabresd:~# insmod /lib/modules/bcmdhd.ko

bcmdhd: Unknown symbol sdio_reset_comm (err 0)

insmod: ERROR: could not insert module /lib/modules/bcmdhd.ko: Unknown symbol in module

Thanks & Regards

Could you copy on this thread the result of "uname -r" as well as "modinfo bcmdhd.ko"?

[veeranjaneyulug]

hi ,

Thanks for your reply.

I attached modinfo below.please find below modinfo .and uname -r you are asking system kernel version? or yocto setup kernel version.uname -r system is 3.13 and my kernel version is 3.14.28.we compiled bcm4329 module from out side kernel. kernel built with yocto setup.Than we copy zImage and imx6q-sabresd.dtb into boot partions.

When you log on your i.MX platform execute the following command: "uname -r" this will print the kernel release. Check it matches the vermagic 3.14.28-1.0.0_ga+g91cf351 from your module. If it does not match it does explain why you have the error message when you try to load the module.

[veeranjaneyulug]

Hi ,

Thanks for your reply.

In the below I copied uname -r and modinfo bcmdhd.ko  .please find below things.

i copied bcm_dhd.ko into /lib/modules/ and /lib/modules/nvram.txt ,,         /lib/firmware/fw_bcmdhd.bin.

Ok the vermagic of the module matches your kernel version.

Now this is how I load the module:

insmod /lib/modules/3.14.38-6UL_ga+ge4944a5/kernel/drivers/net/wireless/bcmdhd/bcmdhd.ko firmware_path=/lib/firmware/bcm/fw_bcmdhd.bin nvram_path=/lib/firmware/bcm/bcmdhd.cal dhd_msg_level=0xffff

You want to have the bcmdhd.ko stored under: /lib/modules/[YOUR_KERNEL_VERSION]/kernel/drivers/net/wireless/bcmdhd/

The firmware should be named: fw_bcmdhd.bin and stored under: /lib/firmware/bcm/

The nvram file should be called: bcmdhd.cal and stored under: /lib/firmware/bcm/ (same place as above)

You can turn on logs with dhd_msg_level

[veeranjaneyulug]

Hi ,

Thanks for your reply.

nvram.txt is same as bcmdhd.cal file? and how to change the crystal frequency and all in nvram.txt file.

we are waiting for your reply and suggestions.

Thanks & regards

Hi

Finally we solve that issue .That is kernel mismatch issue.we built fresh out side the kernel.

First we changed <yocto_kernel _source/git>/drivers/mmc/core/sdio.c file we added one dummy function as per community guidence.

on target board we run below command

insmod /lib/modules/3.14.28-1.0.0_ga+g91cf351/kernel/drivers/net/wireless/bcmdhd/bcmdhd.ko firmware_path=/lib/firmware/bcm/fw_bcmdhd.bin nvram_path=/lib/firmware/bcm/nvram.txt

finally we got below error.please find below log and then give me suggestions and idea on that issue.

dhd_module_init in

no wifi platform data, skip

DHD wifi platform data is required for Android build

dhd_module_init: Failed to load the driver, try cnt 3

Make sure that your card is detected as a mmc device first.

You should get a log similar to this. My wifi card is on usdhc1.

mmc0: queuing unknown CIS tuple 0x91 (3 bytes)

mmc0: new high speed SDIO card at address 0001

[mickaeltoumi]

I have seen those logs before and in my case that would happen when the driver is loaded and the radio is not available or detected over SDIO.

How do you connect your Broadcom radio to the i.MX6? Do you have an evaluation boards? please provide as many details as possible.
