我正在尝试使用 tftp 为 zynq 启动 VxWOrks。
我已相应地为 ipaddr、serverip、网络掩码设置了环境变量，并且文件已成功加载到 RAM 中。但是，尝试启动 vxWorks 映像时出现以下错误。VxWOrks 映像没有问题，因为当我将这些文件写入 SD 卡并从 sd 卡启动时，我可以使用这些 iamges 成功启动

zynq-uboot> bootm 0x5000000 - 0x4000000

#ERROR: booting os 'Unknown OS' (14) is not supported"

这是一个完整的屏幕截图

解决方案：我也必须加载 vxWorks.bin 并且它有效。

zynq-uboot> tftp 0x200000 vxWorks.bin
