Actually i am using

Sdk : ti-processor-sdk-linux-am57xx-evm-03.00.00.04

Board : custom board

Hardware : WL1835

Software : linux-4.4.12

I have verified voltages, Vbat:3.1v and vio:1.7v and WL_EN is 1.7v.

diff .config arch/arm/configs/tisdk_am57xx-evm_defconfig

> # CONFIG_WL_TI is not set

wl18xx , wlcore , mac80211 , cfg80211 , wlcore_sdio are loaded auto into board .

In addition, my WL1835 driver is the official used to own , If the driver can support provided by the official of my system . About this drive I am a official used to own or compat-wireless .

please help me it is hardware issue or software issue.

Thanks & Regards.

Hi,

1. What is the board you are using, is it an am57xx-evm or you own target hardware?
2. Can you paste the full kernel boot log (from power up)
3. Please attach your full kernel .config

BR,
Eyal

Hi there,

Based on the error log it seems like the driver is crashing when probing wlcore_sdio.ko on an sdio bus access failure:
[ 31.871090] wl1271_sdio mmc2:0001:2: sdio write failed (-84)

The module is previously probed ok on the sdio bus so basic connection is there:
[ 2.403832] mmc2: queuing unknown CIS tuple 0x91 (3 bytes)
[ 2.409648] Power Management for TI OMAP4+ devices.
[ 2.410303] mmc2: new SDIO card at address 0001

Is this a custom board or an EVM?
My suggestion is try working first with a slow SDIO clock and see if it helps.
As it could be some tuning issue on the sdio bus.

You can lower the bus speed using by adding the following in the mmc4 sub-node to lower the clock to 5Mhz:

max-frequency = <5000000>;

BR,
Eyal

Dear Eyal,

This is my revised configuration file.

CONFIG_WL_TI=y
# CONFIG_WL1251 is not set
# CONFIG_WL12XX is not set
CONFIG_WL18XX=m
CONFIG_WLCORE=m
# CONFIG_WLCORE_SPI is not set
CONFIG_WLCORE_SDIO=m
CONFIG_WILINK_PLATFORM_DATA=y

I feel that the kernel configuration file may not be so configured, do you think?

Thanks.

This looks ok, but i don't think your issue is related to the kernel .config.
Please try lowering the SDIO bus clock as suggested above and see if it helps.

Still looks like the same issue (sdio read fail).
try lowering it even more (1Mhz) and also consult a hardware engineer for probing the sdio lines and verify signal integrity.

BTW, have you followed this document while making the board?:

Dear Eyal,

Thanks for your reply.

When I changed to 1Mhz print information is as follows:

[ 8.391306] wlcore: wl18xx HW: 183x or 180x, PG 2.2 (ROM 0x11)

[ 8.430703] wlcore: chip id 0x6030111 (185x PG20)

[ 8.502049] wlcore: loaded

And ifconfig -a after the emergence of the wlan0 :

root@am57xx-evm:~# ifconfig -a

But when I iwlist wlan0 scanning when the following information:

Is it a hardware problem?

You should try:

Instead of iwlist.

I can start wlan0 , can also be networked.

But why 5Mhz and 50Mhz can not be used?

And when I use 1Mhz very unstable, and often there will be the following print information :

Hi,

As you are able to work (partially) using a lower SDIO spped, the issue is most likely a hardware issue with the sdio bus of your custom board.
What level shifter was used in the design ( for 3.3->1.8V translation ?
Did you follow the level shifting document i pointed you to earlier?
Did you ask your hardware engineers to look at the sdio bus signals (using a scope) and verify the signal integrity?

BR,
Eyal

Dear Eyal,

Thanks for your reply.

I use the level shifter model is LSF0108QPWRQ1.

Here is my schematic :

Is there any problem with this connection?

Thanks.

TI__Mastermind 20285 points

Hi,

Normally, you should have used TXS0108. This is what most designs use, and as shown in:
www.ti.com/.../swra448a.pdf

I have forwarded it also to our H/W expert to comment regarding the feasibility of using the LSF.

BR,
Eyal

Dear Eyal,

Thank you for forwarding, I will wait for your H / W expert advice.

Some suggestions from our hardware team:

1. Scope the SDIO lines and take snap shots at several clocks
2. Try to pull the sdio lines with a 10k resistor to 1.8V on the WL8 side with existing LS (D0,D1,D2,D3,CMD) and take snap shots again
3. If it doesn’t work Try to replace with the TXS0108 Variant and measure again

BR,
Eyal

Hi Eyal,

I have been on the side of the 10k pull up the resistance, can support 1M frequency, but 5M and 50M or not.

Should I pull both sides at the same time?

Every pin need pull-up?

Or change the size of the resistor , because I saw the LSF0108.pdf wrote:

9.2.1.2.2 Pull-up Resistor Sizing
The pull-up resistor value needs to limit the current through the pass transistor when it is in the ON state to about
15 mA. This ensures a pass voltage of 260 mV to 350 mV. If the current through the pass transistor is higher
than 15 mA, the pass voltage also is higher in the ON state. To set the current through each pass transistor at 15
mA, to calculate the pull-up resistor value use the following equation:
Rpu = (Vpu – 0.35 V) / 0.015 A

Hi Eyal,

I tried in the 1.8v side of the pull-up 1K, 3.3V side pull-up 2K.
The result is to support 2M, 2.5M very unstable.

When I reduced the pull-up resistor to 100ohm and 240ohm.

The frequency did not increase and the result was the same as if there was no pull-up.

What's the reason?

Thanks.

TI__Mastermind 20285 points

Hi,

The best suggestion I have right now is to try and replace the LSF0108 with the TXS0108.
This is the LS that most customers use.

Otherwise you need to probe all the sdio lies using an oscilloscope a during sdio bus operations and check the signals.
There is not much we can say without actually seeing the wave forms.

BR,
Eyal

Hi Eyal.

Thanks for your reply.

I can refer to the EVM design?

Below is the circuit schematic.

Why WL_EN, IRQ, CLK and CMD 、D0-D3 to use a different chip .

Can not they use the same TXS0108 conversion?

Or is it because these signals affect each other?

Thanks.

0 Eyal Reizer over 8 years ago in reply to Better Louis

TI__Mastermind 20285 points

Hi,

Yes, they can use the same TXS0108.
See for example the beaglebone black wireless board schematics for reference.

Hi Eyal.

Thanks for your reply.
My problem is solved, the circuit is connected In addition to the problem, the use of LSF0108 is feasible.
Thanks.

Hi,

Thank you for the update.

Just for knowledge, what was the fix you have done in order to make it work correctly?

Hi Eyal.

I have a piece of hardware and MMC_DAT2 shared, no problem after the break, it should be the reason for the use of the wifi.
