Tool/software:
Hi,
I've try to configure the nor-spi on sdk 10 version, compiling using yocto,
here is my dts node: (u-boot dts)
&ospi0 {
bootph-all;
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&mcu_fss0_ospi0_pins_default>, <&mcu_fss0_ospi0_1_pins_default>;
ospi0_nor: flash@0 {
status = "okay";
compatible = "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <25000000>;
spi-tx-bus-width = <8>;
spi-rx-bus-width = <8>;
cdns,tshsl-ns = <10>;
cdns,tsd2d-ns = <30>;
cdns,tchsh-ns = <2>;
cdns,tslch-ns = <2>;
cdns,read-delay = <4>;
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 {
bootph-all;
label = "ospi.phypattern";
reg = <0x3fc0000 0x40000>;
};
};
};
};
But, it doesn't work, I'm getting following error while try to probe from U-boot CLI

Resetting CPU ...
from this my understanding is, the sub node which is related to spi-nor is missing
could you help me on this?
