Hi All,


I am not able to make the Bluetooth controller working on the IMX8M mini evk. I made an fsl-image-machine-test and test the wifi interface without any problem.


Here are the steps I made to make bluetooth working:


root@imx8mmevk: ~# systemctl start bluetooth

root@imx8mmevk: ~# hciconfig hci0 up

Can't get device info: No such device

root@imx8mmevk: ~# bluetoothctl

Agent Registered

[bluetooth]# devices

No default controller available

[bluetooth]# quit

root@imx8mmevk: ~# hciattach /dev/ttymxc2 qca
frame_hci_cmd_pkt: Sending EDL_PATCH_VER_REQ_CMD
HCI-CMD -1:     0x1     0x0     0xfc    0x1     0x19
read_vs_hci_event: Wait for HCI-Vendor Specfic Event from SOC
wait_for_data: Timing out on select for 3 secs.
hci_send_vs_cmd: Failed to get HCI-VS Event from SOC
Failed to attach the patch payload to the Controller!
qca_soc_init: Fail to get Rome Version (0xffffff92)
Initialization timed out.
