bluetooth problem in Android P

[Mohammad Saleh Dehghanpour]

I have a test board for amlogic S905X chip. (p212 reference board) When I burn my ROM into it, the bluetooth constantly shows "stopping" dialog.

The logfile (tombstone) is detailed but the important part is here:

01-01 00:24:15.708 28953 28986 I bt_hci  : hci_initialize

01-01 00:24:15.710 28953 28970 D bt_hci  : hci_module_start_up starting async portion

01-01 00:24:15.711 28953 28986 I bt_hci  : hci_initialize: IBluetoothHci::getService() returned 0xa1b91560 (remote)

01-01 00:24:16.209 28953 28987 F         : [0101/002416.209517:FATAL:hci_layer_android.cc(78)] Check failed: status == Status::SUCCESS. 

It seems the hardware is initialized but the the HCI can not be started. Is it related to kernel drivers or android user space and HAL modules? or even framework(?!)

How can I approach this problem to solve it?

the full log file is pasted here: https://paste.ubuntu.com/p/J524z6BhJc/

By default, Bluetooth will be initialized with hci0 interface. Please check whether this interface is available. If not, it is kernel issue. Otherwise, Android HAL. I think!
