MAYA-W1 device tree setting ?

Hello,

I have connected MAYA-W1 to my device using SDIO

but I think something is missing in my device tree, because I see in the dmesg this messge:

"mmc1: SDHCI controller on b0000000.sdio-host [b0000000.sdio-host] using ADMA"

while in the PDF it said I need to see it as :

"mmc1: new ultra high speed DDR50 SDIO card at address 0001"

 

up until now the sdio was for sdcard

this is the device tree setting:

"

 

sdmmc1: sdio-host@b0000000 {
bus-width = <4>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_sdmmc1_default>;
status = "okay";
};
 
 
pinctrl_sdmmc1_default: sdmmc1_default {
cmd_data {
pinmux = <PIN_PA28__SDMMC1_CMD>,
<PIN_PA18__SDMMC1_DAT0>,
<PIN_PA19__SDMMC1_DAT1>,
<PIN_PA20__SDMMC1_DAT2>,
<PIN_PA21__SDMMC1_DAT3>;
bias-disable;
};

conf-ck_cd {
pinmux = <PIN_PA22__SDMMC1_CK>,
<PIN_PA30__SDMMC1_CD>;
bias-disable;
};
"

what is missing \ need to add in order to see the device correct?

I have install the drivers \ bin file like it said in the PDF - but still nothing so this is why I think it's something in the device tree setting

 

Thanks ,

Hello @Da_123456_DA 

 

We defend pinctrl_usdhc2_200mhz and pinctrl_usdhc2_100mhz for sdio high-speed mode, you should follow the reference manual to defined pad ctrl register. like below:

pinctrl_usdhc2_100mhz: usdhc2-100mhzgrp {
fsl,pins = <
MX8MM_IOMUXC_SD2_CLK_USDHC2_CLK 0x194
MX8MM_IOMUXC_SD2_CMD_USDHC2_CMD 0x1d4
MX8MM_IOMUXC_SD2_DATA0_USDHC2_DATA0 0x1d4
MX8MM_IOMUXC_SD2_DATA1_USDHC2_DATA1 0x1d4
MX8MM_IOMUXC_SD2_DATA2_USDHC2_DATA2 0x1d4
MX8MM_IOMUXC_SD2_DATA3_USDHC2_DATA3 0x1d4
MX8MM_IOMUXC_GPIO1_IO04_USDHC2_VSELECT 0x1d0
>;
};
 
pinctrl_usdhc2_200mhz: usdhc2-200mhzgrp {
fsl,pins = <
MX8MM_IOMUXC_SD2_CLK_USDHC2_CLK 0x196
MX8MM_IOMUXC_SD2_CMD_USDHC2_CMD 0x1d6
MX8MM_IOMUXC_SD2_DATA0_USDHC2_DATA0 0x1d6
MX8MM_IOMUXC_SD2_DATA1_USDHC2_DATA1 0x1d6
MX8MM_IOMUXC_SD2_DATA2_USDHC2_DATA2 0x1d6
MX8MM_IOMUXC_SD2_DATA3_USDHC2_DATA3 0x1d6
MX8MM_IOMUXC_GPIO1_IO04_USDHC2_VSELECT 0x1d0
>;
};

I need to see how to I define this on Microchip device using Linux4sam

because the pins are not the same , and it's confusing

I have ask then also

but now I can refer them to this setting, and see how I can "copy" according to what is needed

Thanks,

Hello @Da_123456_DA 

 

I guess you are not using i.MX platform, you should firstly check if host support 1.8V. high speed sdio only works on 1.8V

 

I also attach i.MX platform sdio configuration to you:

&usdhc2 {
        assigned-clocks = <&clk IMX8MM_CLK_USDHC2>;
        assigned-clock-rates = <200000000>;
        pinctrl-names = "default", "state_100mhz", "state_200mhz";
        pinctrl-0 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
        pinctrl-1 = <&pinctrl_usdhc2_100mhz>, <&pinctrl_usdhc2_gpio>;
        pinctrl-2 = <&pinctrl_usdhc2_200mhz>, <&pinctrl_usdhc2_gpio>;
        cd-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;
        bus-width = <4>;
        vmmc-supply = <&reg_usdhc2_vmmc>;
        status = "okay";
};

 

Best Regards

I'm using Microchip SOM SAMA5D27

if I enter a SD card - it's working , and I have check the power is 1.8V

 

how can I marge between the information you send me about the device tree configuration and my own configuration ?

I can't understand what I need to change in my file

 

can you help me with this ?

 

Thanks ,

Hello @Da_123456_DA 

 

About dts configuration, I recommend you contact microchip support. For Wi-Fi side, if you want our Wi-Fi module works on high-speed mode, just make sure sdio interfaces works at 1.8V.

Can you maybe explain what every pins mean - and then I will try to see what this pins mean in Microchip?

I know the MMC DATA pins are:

<PIN_PA18__SDMMC1_DAT0>,
<PIN_PA19__SDMMC1_DAT1>,
<PIN_PA20__SDMMC1_DAT2>,
<PIN_PA21__SDMMC1_DAT3>;

 

the clock and CD are :

<PIN_PA22__SDMMC1_CK>,
<PIN_PA30__SDMMC1_CD>;

 

 

the mmc pins are :

bus-width = <4>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_sdmmc1_default>;
status = "okay";

 

so how can I compare it to you device tree setting ?

I have found this :

{
model = "Microchip SAMA5D27 SOM with WLAN MAYA-W1";

/* Define GPIO controller node */
pinctrl {
/* Define pin configurations for WLAN MAYA-W1 */
wilc_sdio_pins: wilc-sdio-pins {
/* Replace these GPIO pins with the correct ones for the SAMA5D27 SOM */
compatible = "atmel,sama5d27-pinctrl";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_mmc1_clk_cmd_dat0 &pinctrl_mmc1_dat1_3>;
};
};

/* Define WLAN MAYA-W1 SDIO controller node */
mmc1: sdio-host@b0000000 {
compatible = "atmel,sama5d27-mci";
reg = <0xb0000000 0x1000>;
interrupts = <8 IRQ_TYPE_LEVEL_HIGH >;
interrupt-parent = <&pioA>;
status = "okay";
};

 

/* Define WLAN MAYA-W1 device node */
wifi: wifi@0 {
compatible = "microchip,wilc1000", "microchip,wilc3000", "atmel,wilc_sdio";
reg = <0>;
/* Replace these GPIO pins with the correct ones for the SAMA5D27 SOM */
reset-gpios = <&pioA PIN_PC14 GPIO_ACTIVE_HIGH>; /* GPIO pin PC14 */
chip_en-gpios = <&pioA PIN_PC10 GPIO_ACTIVE_HIGH>; /* GPIO pin PC10 */
interrupt-parent = <&pioA>;
interrupts = <2 IRQ_TYPE_LEVEL_HIGH 7>; /* Example: GPIO pin A2 */
status = "okay";
};
};

 

but I can't understand how to use your setting with this setting .

 

can you guide\help?

Hello @Da_123456_DA 

 

I'm not very familiar with microchip product. So, I just share my idea to you. 

Following parameter is used to decided sdio speed.

pinctrl-0 = <&pinctrl_sdmmc1_default>;

According to my experience, default is 50M, in i.MX we also defined 100M and 200M. So that Wi-Fi card can work in high-speed mode.

But before that, please make sure host sdio interface pins support high-speed mode. And sdio works under 1.8V.

You could share full dts file to us then I can have a look.

 

Best Regards

Shaun

this is my device_tree (there are many pins not in use - so don't be afraid to tell me to change them )
