  • 我将您的问题升级到了英文论坛,会有相关专家给你支持。

    e2e.ti.com/.../sk-tda4vm-the-evm-board-often-crashes-when-running-or-no-loading

  • 您好,我看到了英文论坛的回复:

    1.我使用的SK-TDAVM修订号:PROC112A1;

    2.空载崩溃时温度及日志见本回复最后;

    3.我的电源符合 (20V/65W)的额定功率,最大输出支持20v/3.25A.

    我尝试重新刷SD卡image(ti-processor-sdk-linux-sk-tda4vm-etcher-image.zip — 1449343 K)复现bug,运行Single input multi inference demo并记录温度日志几分钟之后出现显示器输出卡死但minicom仍在显示demo运行,温度监控日志也在继续。然后,我退出demo,重新进入任何demo出现Segmentation fault (core dumped) 错误(下面列出),无法运行demo。Reset后,demo可以运行,但出现不定时崩溃(最新一次空载时崩溃日志及对应温度将在下面列出,崩溃时显示器仍然在显示壁纸,但无法进行任何操作,包括UART及SSH进行控制)。

    日志如下:

    Segmentation fault (core dumped) 错误:

    请帮助转到英文论坛再次分析原因,谢谢。

  • 您好,英文论坛仍无最新回复解决方案,同时我使用同样的SD卡及其他同样硬件测试了同型号的其它SK-TDA4VM,未出现这样的问题,因此我推断是我购买的这个SK-TDA4VM存在硬件缺陷,我该如何寻求售后服务?谢谢

  • 请按照以下方式联系客户支持部门的技术部门,会有技术客服为您提供帮助。

    • 打开链接https://ticsc.service-now.com/csm
    • 点击申请新的支持下面的提交申请按钮
    • 在新打开的窗口中点击技术支持下面的创建案例按钮
    • 在打开的表格中您可以使用中文描述您的问题并且递交。递交申请时,请您提及以下信息:
      • Ti.com购买订单号
      • 需要技术鉴定EVM是否存在质量问题
      • 您是否使用免费邮箱注册myti账号
  • 英文论坛已有回复。

  • 您好,我看到了英文论坛的回复,做出回复如下,请帮助跟进:

    首先,出现这种情况不仅在运行演示时。

    1.运行演示时,我使用的是文件输入;
    2.开机后不运行任何应用程序,这个错误是不定时出现的,之前测试中最短时间约为开机三分钟左右,很抱歉我没有更多时间进行测试10次出现的概率;
    3.我有多个开发板,目前使用问题板上的SD卡镜像以及其他外设相同的情况下,仅更换我的其他相同型号开发板使用至今未出现类似情况,一直正常使用,因此,我判断这个开发板存在硬件缺陷。
    4.我尝试更换其他SD卡,依然出现这种情况。

    5.经过我的测试,这种情况出现的可能过程:①刷写SD卡image后装载开发板进行开机②运行demo十分钟左右③显示器显示画面卡停,此时通过键盘终止demo,重新运行程序失败④重启开发板后即出现这种情况不定时死机

    最重要的一点是我是用同样的环境进更换我的同型号其他开发板未出现这种情况,因此我初步判定此开发板存在质量问题,请您帮助我确认此开发板是否存在质量问题,然后我将进行售后更换申请,谢谢。

  • 已跟进给工程师了哈。

  • 您好,可以帮助催促一下工程师吗?这个问题拖的时间太久了,我想尽快得到工程师是否为开发板质量问题的回复,以便售后更换一个新的开发板。谢谢。

  • 您好,

    确认了哈,应该是starter kit有问题,您可以在此处申请相应的更换:https://www.ti.com/productreturns/docs/createReturn.tsp

    详情您可以参阅英文论坛的答复。
