hello,
I have winbond w25n02jw flash IC. I and try to communicate over QSPI. but I am not able to detect that. please help me.
In dts file:
&ospi0 {
flash@0 {
compatible = "jedec,spi-nand","winbond,w25n02jw";
reg = <0x0>;
spi-tx-bus-width = <4>;
spi-rx-bus-width = <4>;
spi-max-frequency = <25000000>;
cdns,tshsl-ns = <60>;
cdns,tsd2d-ns = <60>;
cdns,tchsh-ns = <60>;
cdns,tslch-ns = <60>;
cdns,read-delay = <4>;
cdns,phy-mode;
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "ospi.tiboot3";
reg = <0x0 0x80000>;
};
partition@80000 {
label = "ospi.tispl";
reg = <0x80000 0x200000>;
};
partition@280000 {
label = "ospi.u-boot";
reg = <0x280000 0x400000>;
};
partition@680000 {
label = "ospi.env";
reg = <0x680000 0x40000>;
};
partition@6c0000 {
label = "ospi.env.backup";
reg = <0x6c0000 0x40000>;
};
partition@800000 {
label = "ospi.rootfs";
reg = <0x800000 0x37c0000>;
};
partition@3fc0000 {
label = "ospi.phypattern";
reg = <0x3fc0000 0x40000>;
};
};
};
};
ospi0_pins_default: ospi0-pins-default {
pinctrl-single,pins = <
AM62X_IOPAD(0x000, PIN_OUTPUT, 0) /* (H24) OSPI0_CLK */
AM62X_IOPAD(0x00c, PIN_INPUT, 0) /* (E25) OSPI0_D0 */
AM62X_IOPAD(0x010, PIN_INPUT, 0) /* (G24) OSPI0_D1 */
AM62X_IOPAD(0x014, PIN_INPUT, 0) /* (F25) OSPI0_D2 */
AM62X_IOPAD(0x018, PIN_INPUT, 0) /* (F24) OSPI0_D3*/
>;
};
&ospi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&ospi0_pins_default>;
};
please can you suggest what should change in my dts. and config flag.
