Linux/WL1837MODCOM8I: SDIO interface fails to initialize

Hi,

Just to add I have following DT node:

mmc@480ad000 {
compatible = "ti,dra7-hsmmc", "ti,omap4-hsmmc";
reg = <0x480ad000 0x400>;
interrupts = <0x0 0x59 0x4>;
ti,hwmods = "mmc3";
ti,needs-special-reset;
dmas = <0xc9 0x4d 0xc9 0x4e>;
dma-names = "tx", "rx";
status = "okay";
sd-uhs-sdr12;
sd-uhs-sdr25;
sd-uhs-sdr50;
vmmc-supply = <0x506>;
bus-width = <4>;
cap-power-off-card;
keep-power-in-suspend;
ti,non-removable;
pinctrl-names = "default", "hs", "sdr12", "sdr25", "sdr50";
pinctrl-0 = <0x500>;
pinctrl-1 = <0x501>;
pinctrl-2 = <0x502>;
pinctrl-3 = <0x503>;
pinctrl-4 = <0x504 0x505>;

#address-cells = <1>;
#size-cells = <0>;
wlcore@0 {
compatible = "ti,wl1837";
reg = <2>;
interrupt-parent = <0xcd>;
interrupts = <9 0x4>; /* IRQ_TYPE_LEVEL_HIGH */
};
};

Referring to link [1] I applied the 3 patches and I am using WILINK_MAINLINE=1 . When I load the modules I dont get any wlan interface created.

[1] processors.wiki.ti.com/.../Add-wilink8-to-processor-sdk-3.0

Thanks,
Mike

Our WiFi expert will get back shortly.

Thanks

Hi,

There are other nodes which are related to wilink.

Have you intialized also wlan_enable and wlan_irq gpios?

Please see for example for the am57xx-evm:

Especially the mmc3 node and the vmmcwl_fixed nodes.

Also, can you attach kernel boot log ao we can look at it and see where it fails?

Best Regards,

Eyal

Hi Eyal,

Yes I have initialized all the pins, during booting I can see CLK and CMD for MMC but no data. Following is my complete pinmux

=================================================

This where it fails " mmc1: error -110 whilst initialising SDIO card" traversing through the code it fails while setting the bus width.

Just to add I have got bluetooth working.

Thanks,

Hi Eyal,

I have proceeded further by adding max-frequency=<15000000>; property in DT. But now I get the kernel warning as follows:

Hi Eyal,

It works with max-frequency=<1000000> thanks!
Will the wifi speed be reduced by this clock ?

Thanks,

Thanks Eyal,

Ill cross check with the hardware team. Just to add we are using twl1200-q1 which is connected to wl1837. would you suggest to drop this and instead connect wl1837 to the processor pins ?

Thanks,
-Mike
