WiLink 1837MOD support in SDK 7.01

Hi Rudresh,

Yes, you can find the prebuilt images at: processors.wiki.ti.com/.../WL18xx_AMxxx_Platform_Integration_Guide

Regards,
Gigi Joseph.

Hi Joseph,
I need the patch for SDK 7.01 to support. By default DTS entry for Wi-link is not there. Also I think firmware fro 1837 is different .
So, please guide us

Regards,
Rudresh

Hi Rudresh,

The link I sent you contains the patch set that are required. Please check that.
The firmware is the same.

Regards,
Gigi Joseph.

Hi Joseph,
We found that there was a wrong settings for pinmux in SDIO. After doing that we are getting following crash.

Hi Joseph,
In the DTS entry following are for edma channels allocation.
&mmc3 {
status = "okay";
/* these are on the crossbar and are outlined in the
xbar-event-map element */
dmas = <&edma 32
&edma 33>;
dma-names = "tx", "rx";
vmmc-supply = <&vmmcwl_fixed>;
bus-width = <4>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&mmc3_pins_default>;
pinctrl-1 = <&mmc3_pins_sleep>;
cap-power-off-card;
keep-power-in-suspend;
ti,non-removable;
};

How the edma values are configured as 32 and 33. This is for am437xx for Wilink SDIO interface.

Regards,
Rudresh
