IMX8MMD4 android wifi/bt issue

135 Views
Contributor III

Hi,

We have purchased imx8mmd4 evk + MX8_DSI_OLDE1 and ready to design follow the schematic.

But we found the wifi and bluetooth are not working, because the wifi/bt is broadcom(cypress) 1MW , not qca,

There is no document to guide how to modify android 9 bsp to make wifi/bt working for imx8mmd4, so after some study and modification (dts/boardconfig), wifi is working now, but bluetooth is still not working, and I got following error message when every time turn on the bluetooth under android (module found, firmware loaded).

Finally I saw the there is a service wcnss_filter for qca module in init.rc, but can't find service for 1mw module, maybe it's the root cause. So I have 2 questions:

1.Are there any document to guide how to enable 1mw wifi/bluetooth and its service/HAL/library? (document from Murata/Cyress are only for linux, no hcitool in android bsp)

2.There is 2 pins used for BT, BT_WAKE_DEV,BT_WAKE_HOST but can't find any definition in dts, I am afraid it's possible BT is sleeping because no driver handle those pin, how to use those pin?

Hope I can get support here.

thank you
