porting bcm43455 wifi driver(bcmdhd) to imx6 + qnx6.6.0

Hi,

   I trying to bring wifi module bcm43455 (similar to bcm4335/bcm4339) on qnx6.6.0 platform.

   All i have is bcmdhd driver for linux/android, how can i port it to qnx system ?

  Thanks!

The QNX network stack offers a shim layer to port NetBSD network drivers over to QNX quite easily. If that works for 
WiFi drivers I cannot tell. Using a Linux/Android source base as a starting point will definitely cause more porting 
effort.
The online help also contains a Network DDK with a sample Ethernet driver. For the additional things for WiFi (e.g. 
interface to WPA-Supplicant) I do not know about samples.

Which interface of the chip are you using? PCIe oder SDIO or UART? In case of SDIO you would also need to look up the 
supplied driver code for the devb-sdmmc driver and extract the SDIO part from it.

Regards,
Albrecht
