Bluetooth, unable to read chip version.

Hi, i am using wl1273 chip with freescale imx6 sabre based custom board. During bluetooth enable, ti-st driver fails to read the chip version and hence reports firmware download error. Ldisc installs succesfully.

I am also able to see the correct response fron chip when verbose is enabled. But there is a line break between the hex codes and that seems to be the problem. Any ideas what may be wrong.

    Hi,

    I think the problem is probably that the flow control on the UART driver needs to be enabled. I certainly saw a similar failure mode with WL18xx on imx6. In dts file define UART with flow control as highlighted.

    &uart4 {

    pinctrl-names = "default";

    pinctrl-0 = <&pinctrl_uart4_1>;

    status = "okay";

    fsl,uart-has-rtscts;      // enable rts/cts usage on uart4

    };

    Here is the log:

    I do have RTS CTS enabled, and flow control enabled.

    is what i think is causing problem. Any suggestions ??

    Hi,

    In the St_kim.c file, in function read_local_version(), using the below code we parse respond and get the required firmware version
    version =
    MAKEWORD(kim_gdata->resp_buffer[12],
    kim_gdata->resp_buffer[13]);
    chip = (version & 0x7C00) >> 10;
    min_ver = (version & 0x007F);
    maj_ver = (version & 0x0380) >> 7;

    if (version & 0x8000)
    maj_ver |= 0x0008;


    In your case the make wore will take the last two parametes amd makeword and give the version as 0x1F0F
    using which if it is parsed you should be getting the script version as TIInit_7.6.15.bts, it is strange to see you are getting TIInit_0.0.0.bts.
    Please double if the something is wrong in this part of the code.

    I think since the response is split by a line break, all the data after 0x04 is neing treated as unknown packets. And since there is a line break it evaluates all other expected parts of the response to be all zeros,

    I tried using hciattach, before uim-sys. It was able to download the firmware correctly but i recieved hci command timeouts and bluedroid restarted. So i dont know if its the setup or the code which is causing problem.

    Hi,

    I don't see any reason for a crash.
    Hope you have followed all the steps from here http://e2e.ti.com/support/wireless_connectivity/f/538/t/294284, on bringing up Bluedroid on android.

    Yes, i have followed all the steps and i do see correct version from the chip but somehow the data from uart is being recieved in parts and thus, its resulting in read version failure.

    Hi sandeep, if cts and rts are interchanged, could it lead to such a situation or in that case chip wont work at all.

    Is it possible to check by removing flow control completely..??

    Neeraj,

    How have you connected RTS and CTS?

    On the i.mx6 you need to connect the uart_rts to wl8 rts and uart_cts to wl8_cts. This is a different naming convention to a TI processor which would assume you crossover the rts and cts lines between devices.

    If you have crossed them over then there may be a pin mux option for these pins to swap them that you can manage via the DTS file. However, I've not investigated that.
