请问t113-s3 tina系统由spi nand flash更换为spi nor flash ？？？的流程是什么 根据 Tina Linux 存储介质切换：eMMC，SPI NAND，SPI NOR，SD Card，SD NAND | 全志在线开发者论坛这个链接的步骤做的镜像tina_t113-100ask_uart3_nor.img烧录失败 下面是我做的修改 : spinand切换spinor
1、cd /home/zyn/t113/tina-d1-h/device/config/chips/t113/configs/100ask vim sys_config.fex
28 ;storage_type = 5
29 storage_type = 3
vim board.dts
758 &spi0 {
759 clock-frequency = <100000000>;
760 pinctrl-0 = <&spi0_pins_a &spi0_pins_b>;
761 pinctrl-1 = <&spi0_pins_c>;
762 pinctrl-names = “default”, “sleep”;
763 /spi-supply = <®_dcdc1>;/
764 spi_slave_mode = <0>;
765 spi0_cs_number = <1>;
766 spi0_cs_bitmap = <1>;
767 // status = “okay”;
768 status = “disabled”;
769
770 spi-nand@0 {
771 compatible = “spi-nand”;
772 spi-max-frequency=<80000000>;
773 reg = <0x0>;
774 spi-rx-bus-width=<0x04>;
775 spi-tx-bus-width=<0x04>;
776 // status=“okay”;
777 status = “disabled”;
778 };

缺少 sun8iw20p1_uart3_nor_defconfig 配置文件。T113的NOR Flash默认配置是UART0（sun8iw20p1_nor_defconfig），
但你的开发板使用的是UART3。
cd /home/zyn/t113/tina-d1-h/lichee/brandy-2.0/u-boot-2018/configs
cp sun8iw20p1_nor_defconfig sun8iw20p1_uart3_nor_defconfig
cat >> sun8iw20p1_uart3_nor_defconfig << ‘EOF’
