MMWCAS-DSP-EVM: TDA2X部署linux，成功进入系统后，网络出现异常

MMWCAS-DSP-EVM配套MMWCAS-RF-EVM使用，采用开发板自带的sdimage_3_7_1.img.xz，能够跑通《mmwave_studio_cascade_user_guide.pdf》里面的演示例程，查看其内核版本:u-boot 2016.05，linux kernel 4.4.84.根据《VisionSDK_Linux_UserGuide.pdf》的步骤部署内核:采用了psdkla-u-boot-REL_VISION_SDK_03_08_00_00.tar.gz与psdkla-kernel-REL_VISION_SDK_03_08_00_00.tar.gz。并依据其它相关文档做了如下更改：

1、MAKECONFIG=tda2xx_cascade_linux_radar in Rules.make

2、采用/ti_components/os_tools/linux/kernel/linux-kernel-addon下的文件对kernel和u-boot打补丁

3、在uenv.txt文件里修改fdtfile=dra7-cascaderadar-infoadas.dtb

4、修改/etc/network/interfaces   /lib/systemd/network/80-container-host0.network  /lib/systemd/system/systemd-networkd.service 使其为静态IP

制作SD启动卡，进入系统，出现如下异常打印信息：

进入系统后，无法ping通PC。

然后我采用《PROCESSOR_SDK_CASCADE_RADAR_03_08_00_00_Binaries_setupwin.exe》里提供的vision_sdk\prebuilt\linux\tda2xx_cascade_linux_radar\hlos\linux\boot里的文件，也出现上述一样的问题。

请问这个问题该如何解决呢，谢谢。

谢谢。我查看了英文论坛，找到了相似的问题，不过那个帖子在DHCP的静态IP下都无法PING通。

我今天试了一下默认的DHCP，连接路由器，就可以ping通了。

按照下述更改静态IP后，就出现PING不过的现象。

请问该如何正确修改文件呢？期待您的答复
