通过boot.scr导入

setenv machid 1029
load mmc 0:1 0x41000000 zImage
load mmc 0:1 0x41800000 suniv-f1c100s-licheepi-nano.dtb
bootz 0x41000000 - 0x41800000

有读 suniv-f1c100s-licheepi-nano.dtb

说明 boot.scr 文件存在并被 u-boot 识别了，

没有发现读 zImage, 是缺这个文件？还是卡片有问题？

zImage也是存在的，没有缺文件

我是的uboot,kernel和buildroot是根据 分享Nano fc100s linux主线5.2(TF卡)+adb+lcd(800*480)+qt5的编译过程

setenv bootm_boot_mode sec
setenv machid 1029
load mmc 0:1 0x41000000 zImage
load mmc 0:1 0x41800000 suniv-f1c100s-licheepi-nano.dtb
bootz 0x41000000 - 0x41800000

粘贴到u-boot 命令行, 手动执行这几行命令看效果。

=> setenv bootm_boot_mode sec
=> setenv machid 1029
=> load mmc 0:1 0x41000000 zImage

执行最后一条后，什么反应也没有
