Hi, Configuring MMC3 for SDIO communiction. I have configured pins as below, but still sdio communication is not up.
If clock is not enabled by default how can it be done in device tree, mmc3_pins: pinmux_mmc3_pins { pinctrl-single,pins = < 0x3C (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat3 */ 0x38 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat2 */ 0x34 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat1 */ 0x30 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_dat0 */ 0x8c (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_clk */ 0x88 (PIN_INPUT_PULLUP | MUX_MODE3) /* mmc2_cmd */ >; }; &mmc3 { /* these are on the crossbar and are outlined in the xbar-event-map element */ dmas = <&edma 32 &edma 33>; dma-names = "tx", "rx"; status = "okay"; vmmc-supply = <&wl12xx_vmmc>; ti,non-removable; bus-width = <4>; cap-power-off-card; pinctrl-names = "default"; pinctrl-0 = <&mmc3_pins>; #address-cells = <1>; #size-cells = <0>; wlcore: wlcore@2 { compatible = "ti,wl1271"; reg = <2>; interrupt-parent = <&gpio0>; interrupts = <26 0x4>; /* gpio 31 */ ref-clock-frequency = <38400000>; }; }; &edma { ti,edma-xbar-event-map = /bits/ 16 <1 32 2 33>; }; -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
