请问：F133-B的V1.0 版本的norflash uboot有什么修改，如何适配？

[huangjun.zopudt]

我自行编译了f133-b的Uboot，如下图中的u-boot-spinor-sun20iw1p1.bin

执行报错如下：

请问，这个版本的uboot需要做哪些调整？

[YuzukiTsuru]

boot0和boot1都需要重新编译

[aozima]

128M的DDR是在哪块代码支持的？

3. SPINOR启动
   3.1. setup.h
   路径：lichee/linux-5.4/include/uapi/asm-generic/setup.h
   1、修改COMMAND_LINE_SIZE宏大小至1024，

3.2. boot_package_nor.cfg
路径：lichee/device/config/f133/configs/default/boot_package_nor.cfg
1、修改item=u-boot, u-boot-spinor.fex为u-boot.fex，

3.3. env.cfg
路径：lichee/device/config/f133/configs/default/env.cfg
1、增加nor_root=/dev/mtdblock5
2、增加
setargs_nor=setenv bootargs ubi.mtd=${mtd_name} ubi.block=0,${root_partition} earlyprintk=${earlyprintk} clk_ignore_unused initcall_debug=${initcall_debug} console=${console} loglevel=${loglevel} root=${nor_root} rootfstype=${rootfstype} init=${init} partitions=${partitions} cma=${cma} snum=${snum} mac_addr=${mac} wifi_mac=${wifi_mac} bt_mac=${bt_mac} specialstr=${specialstr} gpt=1

3、修改bootcmd=run setargs_nor boot_normal
参考图如下：

3.4. board.dts
路径：lichee/device/config/f133/configs/evb1/linux-5.4/board.dts
1、增加spi-nor@0结点的配置,并确保节点spi0和子节点spi-nor@0的status="okay"，如下:
spi-nor@0 {
compatible = "jedec,spi-nor";
spi-max-frequency=<30000000>;
reg = <0x0>;
spi-rx-bus-width=<0x01>;
spi-tx-bus-width=<0x01>;
status="okay";
};
参考图如下：

3.5. sys_config.fex配置文件
路径：device\config\chips\f133\configs\evb1
1、修改storage_type = 3

3.6. kernel_menuconfig配置
1、进入make kernel_menuconfig -> Device Drivers -> Memory Technology Device (MTD) Support，选择SUNXI partitioning support和SPI-NOR device support配置；
2、进入make kernel_menuconfig -> Device Drivers -> SPI support，选择SPI memory externsion；

选择SPI memory externsion

3.8. sys_partition_nor.fex
路径：device/config/chips/f133/configs/evb1/sys_partition_nor.fex
此文件为spinor的分区配置文件，打包过程中可能出现分区太小导致镜像装载失败的情况

此时需要修改对应分区大小，或对内核或者文件系统进行裁剪。
各分区大小配置参考样本如下：

3.9. 问题归纳
1）启动过程中，看到如下打印，才能确认spinorflash工作正常，否则请确认spi的gpio配置是否有冲突，或者spinorflash驱动和dts是否配置正常。
