Hi there,
I'm developing a device based on iMX6UL and I need to enabled SAI1 with
MCLK as output (generated internally). I define SAI1 and iomuxc as
follows above and I can see in .../pinctrl-maps file that those pins
have been asigned to SAI1. But I can't get this signals in the
oscilloscope (neither MCLK). Have any of you experience with this?
Regards!
/*imx6ul.dtsi:*/
sai1: sai@02028000 {
compatible = "fsl,imx6ul-sai",
"fsl,imx6sx-sai";
reg = <0x02028000 0x4000>, <0x02028008 0x0500>;
interrupts = <GIC_SPI 97 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clks IMX6UL_CLK_SAI1_IPG>,
<&clks IMX6UL_CLK_DUMMY>,
<&clks IMX6UL_CLK_SAI1>,
<&clks 0>, <&clks 0>;
clock-names = "bus", "mclk0", "mclk1", "mclk2",
"mclk3";
dma-names = "rx", "tx";
dmas = <&sdma 35 24 0>, <&sdma 36 24 0>;
status = "disabled";
};
