Hi TI team,
Can we use "MMC1" to connect to SDIO WiFi (like WL18xx )?
If yes, Is there any limitation in using MMC1 with SDIO WiFi?
From Will Hsu
Hi Biser
Our WiFi module uses the SDIO3.0 standard, and connect to MMC1.
However, during the system startup, the following information is printed:
mmc0: error -16 whilst initialising SDIO card
The following is the device tree configuration of MMC1:
&mmc1 {
status = "okay";
vmmc-supply = <&ldo1_reg>;
bus-width = <4>;
pinctrl-names = "default";
keep-power-in-suspend;
ti,non-removable;
/delete-property/ ti,dual-volt;
pinctrl-names = "default", "hs", "sdr12", "sdr25", "sdr50";
/delete-property/ sd-uhs-sdr104;
/delete-property/ sd-uhs-sdr50;
/delete-property/ sd-uhs-ddr50;
/delete-property/ sd-uhs-sdr25;
/delete-property/ sd-uhs-sdr12;
};
could you please help check where is wrong? thanks！
Hello,
Try reducing the mmc frequency by adding a property in DT node 'max-frequency' try with lower first 1Mhz. And once it initializes correctly try increasing the frequency until SDIO fails to initialize. For example your DT node should look as below:
&mmc1 {
status = "okay";
vmmc-supply = <&ldo1_reg>;
bus-width = <4>;
pinctrl-names = "default";
keep-power-in-suspend;
ti,non-removable;
/delete-property/ ti,dual-volt;
pinctrl-names = "default", "hs", "sdr12", "sdr25", "sdr50";
max-frequency=<1000000>;
/delete-property/ sd-uhs-sdr104;
/delete-property/ sd-uhs-sdr50;
/delete-property/ sd-uhs-ddr50;
/delete-property/ sd-uhs-sdr25;
/delete-property/ sd-uhs-sdr12;
};

Hi Prabhakar:
When I increased to 4MHz, it initializes fail. So I set 'max-frequency' 3MHz. But our Wifi still can't work normally. Whether this frequency is too low to make Wifi work normally?
Hi Prabhakar:
When I insmod Wifi module, the following information is printed:
wlan_sdio: probe of mmc0:0001:1 failed with error -16
But the mmc0 device has been generated in /sys/class/mmc_host/mmc0/ .
Do you have any suggestions for debugging?
Hi Prabhakar:
Now we connect our Wifi module to MMC4, the following information is printed:
mmc2: error -110 whilst initialising SDIO card
The following is the device tree configuration of MMC4:
&mmc4 {
status = "okay";
vmmc-supply = <&vdd_3v3>;
bus-width = <4>;
pinctrl-names = "default";
cap-power-off-card;
keep-power-in-suspend;
ti,non-removable;
pinctrl-names = "default", "hs", "sdr12", "sdr25";
pinctrl-0 = <&mmc4_pins_default>;
pinctrl-1 = <&mmc4_pins_hs>;
pinctrl-2 = <&mmc4_pins_sdr12>;
pinctrl-3 = <&mmc4_pins_sdr25>;
#address-cells = <1>;
#size-cells = <0>;
};
could you please help check where is wrong? thanks！

Hello,
Can you check the MMC_IO_DELAY registers by dumping the values, they have been set to proper values (using devmem2) ?

Hi Prabhakar:
1、I have tried to set in mux_data.h in u-boot, but the result is the same.
2、I have seen the following description in AM57xx Sitara™ IO Configuration Requirements(page 2):
1 Introduction
To ensure the IO timing values published in the Timing Requirements and Switching Characteristics tables
of the AM57xx data manual over the lifetime of the device, the AM57xx software must implement the
proper pad configuration requirements. The impact of not following these requirements may not be
observed immediately. However, in the long term, failure to adhere to this procedure may cause system
issues.
So, I think even if IO delay is not configured, the function should be normal, but there will be problems with long-term use.
Hi Prabhakar:
The hardware changes were too large when connect to the mmc4, so we want to connect to mmc3.
However, the following error occurred when loading the driver:

Hi Prabhakar:
Since working on mmc4 is normal, we think both wifi module and driver have no problems.
Our wifi module is AW-CB178NF.
Dmesg information are visible in attachments
Could you give me some advice?
Are you at least seeing this message
[ 555.787321] mmc0: queuing unknown CIS tuple 0x01 (3 bytes)
The message shows that the SDIO code can read from the card. I'm still looking into this.
Steve K.
Hi, Steve
I haven't seen this message.
Please see my log below.
e2e.ti.com/.../2243880
Are you testing wifi on MMC1 ?
From Will Hsu
Yes, I am using mmc1. But I get the -16 error just like you do and that is EBUSY. I'm still investigating.
Steve K.
You can use mmc1 for SDIO. I have a Qualcomm/Atheros SDIO WLAN card on mmc1. To get it to work I had to revert this patch https://fr.osdn.net/projects/android-x86/scm/git/kernel/commits/5d3f6ef04d65dda92a3573841a7215fb05c347de and change the max-frequency to 64MHz. We're still investigating why it's not working at 192MHz.
Which WLAN are you using? And is the processor SR2.0 (you can read the ID_CODE register at 0x4AE0C204; it should be 0x2B99002F for SR2.0)?
Steve K.
Now we want to upgrade SDK, which version of SDK can be downloaded from the TI official website to solve this problem.
Can you revert (remove) the patch and set max-frequency to 64MHz? I've tested this on the 4.4 kernel and the 4.9 kernel and making these changes works.
Can you enable MMC debug in your kernel config? Then, after you see errors, type in 'dmesg >wlanfail.log'' and attach the file.
What brand SDIO WLAN are you using? Is it on the board or inserted into a slot?
Steve K.
