1. 前言
承接上篇 https://www.ebaina.com/articles/140000012769
2. pe_test.sh支持USB2.0 & USB3.0测试目前，在pe_test.sh中启用USB2.0检查，如下所示
test_and_check_init “usb storage” “lsusb -t” “Mass Storage, Driver=usb-storage, 480M”如果您想使用USB 3.0，启用以下代码 并注释掉USB2.0检查
test_and_check_init “usb storage” “lsusb -t ; sleep 1” “Mass Storage, Driver=usb-storage, 5000M”只要插入u盘并重启设备就可以了
如果eth0连接正确，USB卡插入 将自动重新启动并重复测试 如果eth0没有连接，可以通过它不重启来确定
3. 查看测试可以拔下u盘停止测试 然后查看/root/pe_log/目录下的日志文件大小
注意:XAVIER NX DEVELOPER KIT环境是没有RTC电池， 所以logfilename datetime是不正确的
4. dump PHY当非工作情况下，可以调试phy的diff值
已经做了mii在CustomBoard，而不是XavierEVK 似乎MII -tool没有一个功能dump MII寄存器与RAW值
