wilink8: bluetooth configuration for creating kim node

alok pawar

Other Parts Discussed in Thread: WL1835MOD, WL1835, WL1837

Hi lian,

I am working on wilink8 (wl1835mod), and trying to configure bluetooth.

For that i do pin muxing and platform data initialization in dts file, bluetooth are connecting on uart5.. below are the my changes.

platform data:----

kim {

        compatible = "kim";
        nshutdown_gpio = <103>;     /*gpio4_io07 */
        dev_name = "/dev/ttymxc4"; /* at uart5 */
        flow_control = <1>;
        baud_rate = <3000000>;
        };

        btwilink {

        compatible = "btwilink";
        };

uart initialization :-

&uart5 {
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_uart5_1>;
        status = "okay";
};

pin muxing:-

uart5 {
                pinctrl_uart5_1: uart5grp-1 {
                        fsl,pins = <
                                MX6QDL_PAD_KEY_ROW1__UART5_RX_DATA 0x1b0b1
                                MX6QDL_PAD_KEY_COL1__UART5_TX_DATA 0x1b0b1
                                MX6QDL_PAD_KEY_ROW4__UART5_CTS_B   0x1b0b1
                                MX6QDL_PAD_KEY_COL4__UART5_RTS_B   0x1b0b1
                                MX6QDL_PAD_KEY_ROW0__GPIO4_IO07    0x1b0b1        /* bt enable pin */
                        >;
                };
        };
------------------------------------------------------------

bt enable pin is connected on gpio4_io07.

i also did changes in linux menuconfig and select the required config options.

But i am not geting kim node, after kernel boot.

when i am runnning uim, i am getting "uim:unable to open /sys/devices/platform/kim/install(No such file or directory).

Please give me some suggestion, and please verify that all the configuration are correct?

Hi Alks,

Attached are the patches I used on an imx6SL with 3.10.17 kernel

I think the main one you are missing is that kim needs to be patched to allow it to read the dts properties. It is missing from Freescale kernel code.

Hi lian,

Thanks for your support.

I used the dts patch and driver patch, after that i was able to see some logs.

But still i am not able to find kim node after kernel up, and getting same uim log(uim:unable to open /sys/devices/platform/kim/install(No such file or directory)

Below are the attached log.

Please give me some suggestion, that what i am missing.

Thanks

Is that the correct log you attached. I couldn't see the UIM message you referred to.

In my log I get:

UIM SYSFS Node Found at /sys/./devices/soc0/kim.16/install
Starting uim-sysfs daemon.
uim:@ main
uim:install = /sys/./devices/soc0/kim.16/install
uim:dev_name = /sys/./devices/soc0/kim.16/dev_name
uim:baud_rate = /sys/./devices/soc0/kim.16/baud_rate
uim:flow_cntrl = /sys/./devices/soc0/kim.16/flow_cntrl

This is triggered by the startup script /etc/init.d/rcS.d/S03uim-sysfs that is part of 0003-add-bt-and-upgrade-to-bluez5-7.patch that I uploaded.

Hi Lian,

My code is updated with the patches.

And i also probed nshutdown_gpio (bt_en) pin which is initially high and toggling when uim running, and after kernel boot it goes low.

Below are the log file attach..and some logs are

------------------

uim:begin polling...

We can assume the firmware has loaded as we move to subsequent step of changing uart speed. So I expect that the problem is the wrong firmware.

For any processor/stack we can take the instructions from the StoneStreetOne installation guide http://processors.wiki.ti.com/index.php/WL18xx_Bluetopia_Platform_Manager_Demo_Guide#Software to get correct firmware.

For WL183x it is TIInit_11.8.32.bts and the latest version is service pack 3.3.

Actual link to wget is https://github.com/TI-ECS/bt-firmware/raw/master/TIInit_11.8.32.bts. It needs to go in /lib/firmware.

Hi Lian,

Thank you for your support.

I am not sure that firmware has been loaded or not. And i am using latest firmware which you suggest.

And i can see the hci0 node. after log-in.

I test my images with different baud rate:-

1. set baud rate-115200 and i got following log:-

root@imx6qsabresd:~# hciconfig hci0 up

2. set baud rate-3,000,000 and logs are:

-----------------------------------------------------------------------------------------------

my queries are:-

what should be the baud rate for wl1835mod in BT case?

I am using correct baud rate(3000000).?

Something i am missing in initialization?

Why it is not able to change the baud rate, still i am using latest one which you suggest?

Please find the full log at different baud rates.

Thanks

Alks

Can't init device hci0: Input/output error (5

Alks,

Can you uncomment the

#define DEBUG

#define VERBOSE

in drivers/misc/ti-st/tty-hci.c

this will allow you to log the activity over the UART. We need to find why you are getting "uim:Invalid response". I'm still suspicious of theTIInit_11_8_32.bts file in use.

Also as a quick sanity check probe the UART lines with a scope to check there is actually activity.

Hi Lian,

Where is the drivers/misc/ti-st/tty-hci.c file, i can't find that in my code. Inside the ti-st folder there are only st_kim.c,st_core.c, st_ll.c.

This "uim:Invalid response", i am getting from the 'read_hci_event' function inside the uim, when it failed.

i put print inside the 'read_hci_event' in while loop

---------------------------------------------------------------------------

/* The first byte identifies the packet type. For HCI event packets, it
* should be 0x04, so we read until we get to the 0x04. */

while (reading) {
                rd = read(fd, buf, 1);
                if (rd <= 0 && rd_retry_count++ < 4) {
                        nanosleep(&tm, NULL);
                        continue;
                } else if (rd_retry_count >= 4) {
                        UIM_VER("function=%s, line=%d, rd_retry_count=%d", __func__ , __LINE__, rd_retry_count);
                        return -1;
                }

                if (buf[0] == RESP_PREFIX) {
                        break;
                }
        }
        count++;
---------------------------------------------------------

and output is

function=read_hci_event, line=101, rd_retry_count=5

---------------------------------------------------------

And inside the read_hci_event, there is a comment which says "For HCI event packets, it should be 0x04, so we read until we get to the 0x04." Means value of 'rd_retry_count' is not correct.

Thanks

Alks

Sorry, I'd looked in my AM335x code base for a quick answer.

In the i.Mx patch file it is added to drivers/misc/ti-st/st_core.c

Thanks Lian,

I defined the Verbose and debug in st_core.c file. But i am not able to see any extra log when kernel up and not also in 'hciconfig hci0 up'.

Please find the attached logs.

Regards

Alks

Hi Alks,

Can you send me the Bluetooth Uart of WL1835 to IMXSololite processor connectivity?

Because we already done the board for wifi bluetooth connection by using WL1835 with sololite processor. we are also facing the problem in bluetooth connectivity. How you connected with RTS and CTS between both ends?

below i have mentioned our connections.

processor pins TO WL1835 pins

UART_TX ------------> UART_RX

UART_RX <-------------- UART_TX

UART_CTS<-------------> UART_CTS

UART_RTS <-------------> UART_RTS

is it correct or not?

Thanks,

Sivakumar

Hi Sundeep Mandava,

Still we are facing the problem in Bluetooth communication. here i have attached the log files for the same. if you have any idea please reply me.

Siva,

There are two ways of starting the Bluetooth and you appear to be mixing them.

1. The device tree file drives BT_EN high on boot and then you use KIM/UIM to initialise WL183x. In this case KIM starts first and then when UIM runs it triggers the firmware download.

2. The device tree file drives BT_EN high on boot and then in user space you use hciattach to download the firmware.

In either case you will see a download error if you have not enabled the use of rts/cts on the UART. This is done as follows

&uart4 {
    pinctrl-names = "default";
    pinctrl-0 = <&pinctrl_uart4_1>;
    status = "okay";
    fsl,uart-has-rtscts;      // enable rts/cts usage on uart4
};

Siva,
That looks like you have not merged the device tree support into the kim driver in the Freescale kernel.
If you look at the link on this message you should find the patches to apply to Freescale kernel for this.

Are you getting issues trying to use 115200 instead?
Have you verified that the UART flow control pins (RTS/CTS) are muxed correctly?

Was the original question ever resolved? I'm seeing very similar behavior as Alks. I'm able to get bluetooth working by having a device tree regulator have the BT_EN line high always, and using hciattach. But when I attempt to use UIM/KIM by removing the regulator, I see various failures.

I've tried a few different orderings to attempt to get UIM/KIM to work. Logs are attached with some explanation of each method below. I've verified from this post replies that we are using the most recent TIInit_11.8.32.bts file as well.

1) Have KIM built into the kernel and start UIM on startup. This failure seems to be due to BT_EN not being high on boot (though I haven't probed BT_EN to verify) since hciattach also fails if attempted before a modprobe of btwilink.

The device tree entry below should handle setting BT_EN high on boot, correct?

kim {                                                                                                                                                                                                
    pinctrl-0 = <&pinctrl_wl18xx>;
    compatible = "kim";
    nshutdown_gpio = <&gpio4 23 GPIO_ACTIVE_HIGH>;
    dev_name = "/dev/ttymxc5";
    flow_cntrl = <1>;
    baud_rate = <3000000>;
};

2) KIM built in again, but manually set BT_EN high before modprobe of btwilink. Verified BT_EN is high as hciattach succeeds if modprobe btwilink is not attempted.
modprobe of btwilink and hciconfig hci0 up still fail after manually setting BT_EN high.

Lain,

Any updates on this? See below for reply detailing similar problem to Alks with logs. I've verified BT_EN is high when the kernel loads, hciattach succeeds but I cannot get UIM/KIM to work correctly. The desire is to use UIM/KIM and btwilink to toggle BT_EN for power up/down of wl1837 bluetooth.

Thanks,

Brandon

TI__Genius 16130 points

Hi Brandon,

I don't have any old builds (kernel 3.x) available to look at now. So I can offer some general comments.

The current recommendation would be to not use UIM/KIM and shared transport any more. It was there in the past as we supported multiple radios on the UART (Bluetooth and GPS) which needed multiplexed - hence the "shared" transport.

Now it is only bluetooth so Bluez can directly access the UART. So my recommendation would be along the lines of.

1. Keep KIM entry in device tree as it allows you to specify the port and GPIO. This is more robust long term solution

2 Remove shared transport from kernel config and UIM from user space.

3. Initially Bluetooth use a script like

#!/bin/sh

GPIO=119

PORT="mxc5"

if [ ! -e /sys/class/gpio/gpio${GPIO} ]

then

# export gpio as output to drive BT_EN

echo ${GPIO} > /sys/class/gpio/export

echo out > /sys/class/gpio/gpio${GPIO}/direction

# now force a release from reset on BT_EN

echo 0 > /sys/class/gpio/gpio${GPIO}/value

sleep 1

echo 1 > /sys/class/gpio/gpio${GPIO}/value

# and now attach which downloads the firmware and creates hci interface

# when hci interface comes up udev detects it and triggers hciconfig hci0 up

hciattach tty${PORT} texas 3000000

4. Once you have that working then change the script to parse the device tree entries to give you GPIO and PORT

You'll need to check exactly where in /proc the kim entries are placed in your kernel build.

Hopefully these give you some pointers that help you.

Iain

0 Brandon Schaefer over 8 years ago in reply to Iain Hunter

Intellectual 290 points

EDIT: Sorry I didn't mention this before, we are using kernel 4.1.15

Thanks for the input. I will go with your suggestion of avoiding UIM/KIM completely and stick with managing BT_EN ourselves with a script similar to what you suggested.

A quick confirmation question. If we turn off BT module by pulling BT_EN low, we'd also need to kill hciattach and start it again, correct?

The process to turn off BT then back on would be:
1.) Kill hciattach
2.) BT_EN low
3.) sleep (if necessary?)
4.) BT_EN high
5.) hciattach (will have to reload firmware and do initialization again)
6.) hciconfig hci0 up

Brandon

0 Iain Hunter over 8 years ago in reply to Brandon Schaefer

TI__Genius 16130 points

Hi Brandon,

You are correct. after each BT_EN cycle of low and then high the firmware needs to be reloaded by hciattach so previous instance of that needs to be killed.
