Bluetooth not working MCIMX8M-EVK kit

[shabbirlimdiwal]

Hi,

I am booting fsl-image-qt5-imx8mqevk-20180802213331.rootfs.sdcard from sd card on my imx8m-evk kit. The version of the linux image is imx-4.9.88-2.1.0-8mm_alpha. The board boots fine but seems like on board bluetooth is not working. I ran below commands to test bluetooth after boot, 

root@imx8mqevk:~# systemctl start bluetooth
root@imx8mqevk:~# bluetoothctl
Agent registered
[bluetooth]# devices
No default controller available
[bluetooth]#

Any idea why ? I am attaching logs during boot for your reference. 

Thanks,

Shabbir

what version do you use? pls check the release note, it seems the Bluetooth is not enabled in the default prebuilt image

pls refer to the 4.9.88 release note, for imx8M, Supports Murata 1CQ (QCA6174A) Wi-Fi/Bluetooth.For i.MX 8MQuad, it needs to add kernel parameter "pci=nomsi" to support Murata 1CQ Wi-Fi. for more detailed information about bluetooth, you can refer to the release note.
