https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1503747/tda4ve-q1-the-custom-vision-application-causes-the-system-to-freeze

器件型号：TDA4VE-Q1

工具/软件：

尊敬的 TI 专家：

我们开发了一个定制视觉应用、在 Linux + RTOS 模式下、在 TDA4VE 上同时执行物体检测和环视。 (使用 SDK r10.1)

但是、系统在重负载下偶尔会冻结。

应用程序在冻结前可以正常运行几个小时。

一旦 发生冻结、UART 会断开连接并无响应、JTAG 无法连接、并且主域和 MCU 域(LD5和 LD6)的电源 LED 关闭。

在系统冻结之前、控制台上没有指示分段故障、内核崩溃或应用程序错误/警告的消息、以下情况除外：

    您好、

    我看不到上面的日志中的任何原因,因为系统可能停止工作.. 我认为 PMIC 错误"[26852.38941] tps6594 0-0048：错误 IRQ 陷阱达到 ILIM、BUCK1过流"会更早看到、不是吗？

    最有可能是某些损坏或某些无效访问导致整个系统停止。 所以我们需要更多详细信息。

    -重现此问题的难易程度如何？  

    -什么是客户视觉应用? 它包含哪些所有组件？  

    -什么是数据流?  

    -它运行多久好?  

    此致、

    您好 、Brijesh、

    感谢您的反馈。

    是的、 在系统(也是 UART)冻结之前会出现 PMIC 错误"[26852.38941] tps6594 0-0048：错误 IRQ 陷阱到达 ILIM、BUCK1过流"。

    对于您的问题、请查看以下答案：

    1.这个问题不容易重现,应用程序可以正常运行几个小时到几天。

    2、客户视觉应用程序同时运行物体检测(TIDL: yolov5s 640x416)和环视,显示屏采用三个管道进行不同的层,请参阅图形架构:

    您好 Christopher、

    再说一次、很难用这些信息找出问题。 我建议逐个节点删除节点、以查看 此节点是否影响总图形。

    您好 、Brijesh、

    我们还进行了以下实验。

    1.在 tidl_od_cam 应用程序中添加 srv 图形、该应用程序称为 tidl_od_cam_srv

    2.只需运行图形、无需任何额外 处理

    3.使用 stress-ng 运行 tidll_od_cam_srv

    在上述情况下、系统在执行几个小时后冻结。

    因此、我们怀疑该问题是由高系统负载引起的。 如果我们移除节点以减少负载、则问题可能不会再次出现。"

    由于系统冻结、UART 和 JTAG 均未响应、并且 LD5/6指示器关闭。 是否有办法初步确定这是软件还是硬件问题？ 例如、我们的 EVM 可能会损坏吗？

    而且、如果 PMIC 的错误消息指示系统稍后可能会复位？

    谢谢、

    此致、

    Christopher
