rockchip的sdk编译时出现Error:Chip is invalid!

完整的log如下

查到代码出错在如下代码

位于<sdk_path>/device/rockchip/common/scripts/mk-updateimg.sh
在93行之前加打印检查变量，发现TAG为‘RK’
在文件<sdk_path>/tools/linux/Linux_Pack_Firmware/rockdev/rk3588-mkupdate.sh也使用了该工具，由此可以初步推测出TAG这个变量本来应该是芯片名称，结果却是‘RK’
查到TAG是在如下代码之中赋值的

TAG=RK$(hexdump -s 21 -n 4 -e '4 "%c"' MiniLoaderAll.bin | rev)

关键是hexdump和MiniLoaderAll.bin，MiniLoaderAll.bin这个是二进制，我们使用hex工具查看，可以发现该文件之中确实有rk3588的字符串，所以问题应该不是处在该文件之中，而是出在hexdump上
运行hexdump读取，“hexdump -s 21 -n 4 -e ‘4 “%c”’ MiniLoaderAll.bin”，提示报错为“zsh: command not found: hexdump”
安装hexdump

sudo apt install bsdmainutils

再次使用build.sh，成功编译
