WIFI module AP6335(bcm4339) start failed

[俊宝胡]

Hi All

our custom product is refer to i.MX6QP SABRE and the modifications are the wifi module, ddr, emmc, ours is AMPAK's AP6335 ,1GB ddr,16GB emmc.

we are porting this module to Linux which use 4.1.15 kernel.

i download BCMDHD-L4.1.15_1.1.0 and extract the new firmware, replace the old firmwares.

Whether to support Linux?

I don't know whether this issues caused by wifi driver, could anyone tell me how to get rid of this issues ?

Every help is very appreciated

[kak-dela007]

Tell me, please, how can I install the driver for the AP6335 module in android (Nibiru)? I do not know how to program, are there ready-made files to unpack them and everything worked?

P.S .: before that, there was a module AP6212 in my device

[chrisfeyerchak]

There are at least two alternative drivers that support the bcm4339 chip: bcmdhd and brcmfmac.  Only one or the other should be loaded.  It appears that both drivers are loaded in this case, which will cause problems.

is the firmware and nvram correctly loaded?
