MMWCAS-DSP-EVM: 利用级联板进行雷达数据采集的时候无法采集到数据,从ssd下载时提示“The no of files captured in the directory is zero! Nothing to transfer!”

Part Number: MMWCAS-DSP-EVM
Other Parts Discussed in Thread: MMWCAS-RF-EVM

TI技术支持的工程师们你们好,我在使用MMWCAS-DSP-EVM以及MMWCAS-RF-EVM板的时候,用mmwavestudio上位机进行雷达数据的采集,使用的是官方提供的Cascade_Configuration_MIMO_Test.lua脚本进行硬件参数配置,配置成功之后利用Cascade_Capture.lua脚本进行雷达数据的采集测试。但是发现无法采集到数据,具体表现为:

1.在采集过程中查看ssd内存放采集数据的文件夹时,会暂时出现master以及slave1-3的数据文件,但是大小为0kb,随后立马被自动删除;

2.从ssd下载数据时mmwavestudio报错提示:“The no of files captured in the directory is zero! Nothing to transfer!”具体报错信息如下:

请问这可能是哪里出了问题?我应该如何排查错误?

  • 你好,

    能否尝试格式化硬盘后再试试?

  • 您好,貌似不是硬盘的问题,因为同样的硬盘在另外一块一样的板子上是能用的。之前采集数据一直都是正常的,但是系统3.3V和GND曾经短暂短路过,之后就出现了这样的情况:

    当断电放置电路板经过一段时间之后,就可以正常采集数据了,并且只要不断电就可以一直正常集采、从SSD下载数据,但是只要重启一次系统后,接下来的一段时间内就都会出现提问里面出现的问题;当再次断电放置电路板经过一段时间之后,就又可以正常采集数据了,以此往复。

    目前观察到的现象就是TDA发热稍微比之前多了一点,除此之外除了提问里的问题之外暂时没有发现任何其他问题了

  • 你好,

    硬件之前出现过问题,现在应该就是硬件问题,我这里也没有更多的建议了。

    Thanks,

    Chris
