1、修改注释了ti-processor-sdk-linux-j7-evm-08_06_01_02/bin/setup-host-check.sh中的Ubuntu 18.04的检查，目前setup.sh成功了。

2、U盘SDK烧系统有问题，具体log如下：

请问您是用的TDA4这个型号吗？是在开发板上测试？具体哪个开发板？

根据这个文档https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/08_06_00_11/exports/docs/linux/Overview/Processor_SDK_Linux_Formatting_SD_Card.html#partitioning-sd-card在PC端烧J721EXSOMXEVM系统，没法成功。
