Hello,
I am working with a new application and now I configure the device tree . I have one FPGA system which communicates with my imx6 by ecspi1 but the fpga is working as master and the ss is only connected to one slave , imx6 in this case.
I read that you need to configure the driver to use it like slave mode. but do I need to change something in my dts file?
ecspi1: ecspi@02008000 { | |
#address-cells = <1>; | |
#size-cells = <0>; | |
compatible = "fsl,imx6q-ecspi", "fsl,imx51-ecspi"; | |
reg = <0x02008000 0x4000>; | |
interrupts = <0 31 IRQ_TYPE_LEVEL_HIGH>; | |
clocks = <&clks IMX6QDL_CLK_ECSPI1>, | |
<&clks IMX6QDL_CLK_ECSPI1>; | |
clock-names = "ipg", "per"; | |
dmas = <&sdma 3 8 1>, <&sdma 4 8 2>; | |
dma-names = "rx", "tx"; | |
status = "disabled"; | |
}; |
pinctrl_ecspi1: ecspi1grp {
fsl,pins = <
MX6QDL_PAD_EIM_D18__ECSPI1_MOSI 0x1B0B0
MX6QDL_PAD_DISP0_DAT20__ECSPI1_SCLK 0x1B0B0
MX6QDL_PAD_EIM_EB2__ECSPI1_SS0 0x1B0B0
>;
};
&ecspi1 { //Microcontroller slave mode
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ecspi1>;
status = "okay";
};
Thanks for your help
Regards
