100MHz，可以当

使用多个vipp通道即可，不需要分时复用

V821已经默认配置overlayfs，直接修改即可

参考 sample_virvi 中的接口，设置摄像头出图分辨率或者vipp缩放

可以自行使用debootstrap或者其他工具生成rootfs，替换到sdk的rootfs配置即可

@iamseer 需要全志客户服务平台的SDK

你在IPC板级切nand了，ipc板级优化设备树大小把不用的都删了

&spi0 {
	pinctrl-0 = <&spi0_pins_default &spi0_pins_cs>;
	pinctrl-1 = <&spi0_pins_sleep>;
	pinctrl-names = "default", "sleep";
	sunxi,spi-bus-mode = <SUNXI_SPI_BUS_NOR>;
	sunxi,spi-cs-mode = <SUNXI_SPI_CS_SOFT>;
	status = "okay";

	spi_board0 {
		device_type = "spi_board0";
		compatible = "spi-nor";
		spi-max-frequency = <100000000>;
		m25p,fast-read = <1>;
		/*individual_lock;*/
		reg = <0x0>;
		spi-rx-bus-width = <4>;
		spi-tx-bus-width = <4>;
		status = "disabled";
	};

	spi-nand@0 {
		compatible = "spi-nand";
		spi-max-frequency=<100000000>;
		reg = <0x0>;
		spi-rx-bus-width=<0x04>;
		spi-tx-bus-width=<0x04>;
		status = "okay";
	};
};

已经启动了，console=tty0 显示在屏幕上了吧
