Bring up bluetooth (wl1837 : NF3107) on dra74x
-------------------------------------------------------------------
We are able to bring up WLAN and facing problem with bluetooth bring up.
We have our custom board (J6) which is connected to MAX14830ETM+ using SPI interface and
the BT module is connected with MAX chip UART port 1 (ttyMAX1) as follows,
SPI ttyMAX1
J6 ----------- MAX14830ETM+ ------------------- NF31087
We have manually made the BT_EN pin high always (from u-boot).
When we are trying to attach the BT module (hciattach /dev/ttyMAX1 texas 115200 noflow),
getting the "Initialization timed out." error. When We probe it (from MAX chip),
RTS : Toggling
High : when we do the hciattach
LOW : After getting "Initialization timed out" error.
CTS : LOW always (no response).
The results are attached here (bt_log.txt).
We have also followed the following link and tried with changing the latest TIInit_11.8.32.bts file but does not help.
e2e.ti.com/.../683824
We stuck here and please help us to go forward.
Thanks,
LAL
