标题: imx6 4.1内核的uboot无法更新fdt，image，uboot
uboot 版本：U-Boot 2016.03-svn203 (Jul 31 2018 - 14:07:04 +0800)
通过pri查看部分信息如下：

update_fdt=run set_net_cmd; if ${get_cmd} ${loadaddr_def} ${file_dtb}; fatwrite mmc ${mmcdev}

{mmcpart} ${loadaddr_def} ${file_dtb} 0x80000 else echo FAIL: Update device tree fail ...; fi;
update_kern=run set_net_cmd; if ${get_cmd} ${loadaddr_def} ${file_image}; fatwrite mmc ${mmcdev}

{mmcpart} ${loadaddr_def} ${file_image} 0x600000 else echo FAIL: Update kernel fail ...; fi;
update_uboot=run set_net_cmd; if ${get_cmd} ${loadaddr_def} ${file_uboot}; then sf probe 0:1; sf erase 0 0x200000; sf write ${loadaddr_def} 0x400 0x80000; else echo FAIL: Update u-boot fail ...; fi;

run update_fdt 和 run update_kern 有语法错误无法运行
run update_uboot 无法成功更新uboot

试了几个svn版本都是这个情况

完整信息如下：

我也遇到这样的问题，后来发现是脚本语法有误，需要if 与then 成对使用参照 update_u-boot
