从这些报错我真没看从出啥问题，也是在网上找，说是没有找到flash,是因为淘宝买的板子更换了flash，需要在u-boot里面重新适配型号：
板子的型号为xt25f128，但是实际u-boot的配置里面不是需要重新更改：
u-boot/arch/arm/dts/suniv-f1c100s-licheepi-nano.dts
&spi0 {
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins_a>;
status = "okay";
flash@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "winbond,xt25f128", "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <40000000>;
};
};

然后重新编译烧录就没有出现如上问题了make -j4:
