Dear Sir or Madam,
Hello. I have a question about Bluetooth(BT) connection in i.MX6DQ.
- Phenomenon 1:
When repeating Bluetooth connection & disconnection, i.MX6 isn't possible to connect BT.
- Phenomenon 2:
When reconstructing Bluetooth continuously, a connection is disconnected within about 30 minutes.
- Frequency of Occurrence: Random
- Both phenomenon displayed the log "Bluetooth: Frame Reassembly Failed"
- The problem occurred in L3.14.28. (din't occur in L3.10.53.)
There is a lot of difference between Linux3.10 and Linux3.14. (/drivers/tty/serial/imx.c)
- The problem doesn't occur when disabling the SDMA of UART.
The error occurs in SDMA and recovery processing isn't done.
So, I think that processing of "imx.c" or "tty_buffer" is doubtful.
Could you gibe me the workaround about this issue?
