Hi

I am using IMX6 custom board which have android JB 4.2 with bluedroid stack,  we r using wl1271 chip for wifi and bluetooth.

Wifi is working fine from linux as i ping to near system.

But BT is not working.Our bluetooth driver and ti-st driver is loaded as i seen in boot logs as well as it created entry in /sys/devices/platform/(kim and btwilink).

changes that i made in board file for Bluetooth.

When we debugg the code then we found that inside the TI-ST driver (st_kim_start function) wait for the ldisc to be installed( in wait_for_completion_timeout() ) .It does not installed on first attempt and retry for 2-3 times and failed to install the ldisk. Which i think is necessary for BT driver to communicate with BT device.

I am attaching the board boot logs with ti-st debug message ON. So  anyone can suggest us that what  modification we have to done to solve the  above mention problem.

Regards

Vikram
