我在Ubuntu 18.04LTS环境下安装Linux-SDK时，按照教程安装V08.06.01.03版本SDK时，进行Yocto build时出现问题
按照教程，我将"/ti-processor-sdk-linux-j7-evm-08_06_01_03"，"gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu"，"gcc-arm-9.2-2019.12-x86_64-arm-none-linux-gnueabihf"文件夹 安装到/opt下
当我执行
TOOLCHAIN_BASE=/opt MACHINE=j7-evm bitbake -k tisdk-default-image
时，报错如下，似乎是因为交叉编译的文件名称不正确？但我并没有正确的文件下载路径，请帮我解决该问题，谢谢！
