Unable to calibrate wl18xx

Other Parts Discussed in Thread: WL1835MODCOM8B, AM3352, WL1835, WL1271

Hello all,

We are using AM3352 custom board and connected to WL1835MODCOM8B module. We have done required configuration in .dts file and .config using menuconfig. Checked power up sequence for WL18XX and it's proper.

Tried to insert module(wlcore,wl18xx,wlcore_sdio) manually using modprobe but no use. Please help us in calibrating module.

Hi,

Most likely this is an issue with the dts file (the module is not getting detected).
As a start, can you share the full boot logs?

Please also let me know the kernel version and the wl18xx driver version.

Regards,
Gigi Joseph.

Hi Gigi Joseph,

Thanks for the quick reply.

I'm using linux-4.1.13 version(ti-processor-sdk-linux-am335x-evm-02.00.01.07). As per our understanding this linux version has inbuilt driver for wl18xx module and we are using the same.

Another thing i noticed is, when i do the modprobe, i get below msg, which looks unusual - what may wrong?

Hi

Hi
below is my changes in the DTS file, is there any problem with the changes?

As mentioned in the reply#2, i have used only drivers available in with the kernel. Is that correct or do i need to add any other driver
There is no clear procedure for the linux-4.1.13 version(ti-processor-sdk-linux-am335x-evm-02.00.01.07 how to compile the wilink module drivers, can you please provide the link?

Hi,

The process is explained in processors.wiki.ti.com/.../WiLink8_Linux_Getting_Started_Guide
I can see that your device is not getting enumerated. Can you check if WLAN_EN goes high during boot up (using a scope)? Do you have the correct mapping in your dts file? Please also check if CONFIG_REGULATOR & CONFIG_REGULATOR_FIXED_VOLTAGE is enabled in your kernel?

Regards,
Gigi Joseph.

Hi,

WLAN_EN is not going high during boot up.

dts: gpio = <&gpio1 29 GPIO_ACTIVE_HIGH>;

root@am335x-evm:~# cat /sys/kernel/debug/gpio
GPIOs 0-31, platform/44e07000.gpio, gpio:
gpio-6 (cd ) in lo IRQ

GPIOs 32-63, platform/4804c000.gpio, gpio:
gpio-61 (wlan-en-regulator ) out lo

GPIOs 64-95, platform/481ac000.gpio, gpio:

GPIOs 96-127, platform/481ae000.gpio, gpio:
root@am335x-evm:~#

By using manual steps like "echo "out" > direction" , " echo 1 > value" WLAN_EN is going high (1.8v) but not during boot up. CONFIG_REGULATOR and CONFIG_REGULATOR_FIXED_VOLTAGE are enabled .

Please let me know how to enable using dts file?

Thanks and Regards,

Lahari

Hi Lahiri,

You might want to debug the regulator if this is the case.
Please check if the values are properly parsed inside "drivers/regulator/fixed.c" and its being toggled inside "drivers/regulator/core.c"

Regards,
Gigi Joseph.

Hello Gigi Joseph,

I checked in fixed.c value of "cfg.ena_gpio_flags" is taking as low. Couldnot see toggling in core.c. when I probe at WL_EN pin..initially it ll be high later goes low

If I comment/remove "enable-active-high" in wlan_en_reg. I'm able to get 1.8v at WL_EN. Am I doing something wrong?

How to remove "wlan-en-regulator: disabling" error??

Regads,

Lahari

TI__Guru* 85400 points

Hi Lahiri,

Do you mean to say that if you remove "enable-active-high", then wl18xx is turning on?
"enable-active-high" => Polarity of GPIO is Active high

Regards,
Gigi Joseph.

Thanks for your response..No progress.. still facing issue in mmc1 SDIO interface.
If I remove "enable-active-high", WL_EN is 1.8V. I'm not sure wl18xx is turned on or not.
How to check WL1835MODCOM8B is turned on or still in off state?

Thanks and Regards,
Lahari

Hi.

The easiest way is to see if wlan0 interface is created. You can check that by "ifconfig -a"
If you don't see it, then please share the full boot logs.

Regards,
Gigi Joseph.

No Gigi, wlan0 is not created. Please find attached boot log

Hi Gigi,

On debugging we got to know that it is failing in mmc_attach_sdio ( mmc_send_io_op_cond ) function for mmc1.
mmc1 is not attached to SDIO so we are not getting wlan0 after ifconfig.
What might be the problem with sdio and mmc1.
Also is there any other way or any output pin to check Wl18xx is active apart from ifconfig?

Thanks and regards,
Lahari

Hi Lahiri,

Please take a look at the Module hardware integration guide and fill out the check list.

Regards,
Gigi Joseph.

Thank u Gigi.. we are referring and verify our connection. in the mean time I have another query.
we are connecting only WLAN related pins using wires and Bluetooth ones are left floating. Can that cause any issue?

Connected pins are
VBAT, WLAN_IRQ,
RX, TX,
WL_EN,
SDIO D3,D2,D1,D0,
SDIO_CMD, SDIO_CLK, SLOW_CLK and ground pins.

Hi,

That should be fine. Please refer to "10.5.1 WLAN Host Interface (SDIO)" in the document. What is Rx/Tx?
Please also verify the slow clock accuracy.

Regards,
Gigi Joseph.

Thanks Gigi.

After checking all connections and changing my .dts file ( adding pullup for WL_EN and WL_IRQ and uncommenting enable-active-high in wlan_en_reg), now I'm able to get MMC1: new high speed SDIO card at address 0001.

But we are getting error as below

Hi Lahiri,

Looks like you have wl18xx up and running.

The error that you are getting seems to be because of crda. Have you built/copied it? Does "/usr/lib/crda/regulatory.bin" exist on your filesystem?

Regards,
Gigi Joseph.

Gigi,

I haven't copied any file explicitly.. regulatory.bin file exists on filesystem

administrator@MYTSP00128:~$ ls /media/administrator/rootfs/usr/lib/crda/

libreg.so regulatory.bin

How to resolve this error? Kindly help

Thanks and regards,

Lahari

Hi Lahiri,

Can you unset "CONFIG_CFG80211_INTERNAL_REGDB" in your defconfig and retry?
It's not needed.

Gigi Joseph.

Thanks a lot Gigi.. It worked. Now no error :)

If we give "/usr/sbin/wpa_supplicant -d -Dnl80211 -c/etc/wpa_supplicant.conf -iwlan0 -B" command getting error.
