https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1535036/am62a7-reboot-command-dont-work

器件型号：AM62A7


工具/软件：

SDK 版本：10_00_00_08

最近、我一直在扩展库 tisdk-tiny-image-am62axx-evm.rootfs.tar.xz 、以缩短引导和刷写时间。

当我尝试使用 reboot 命令时、系统无法正常重新启动。 以下是日志：

同样,当我使用命令时 shutdown -h now,日志显示如下,但电路板的工作电流没有降低。 我的文件系统是否会丢失某些内容？

    您好：

    您对 AM62A 使用哪种引导方法？

    您是否尝试过其他预构建映像以查看是否也会发生此情况？

    谢谢、

    嗨、Anshu

    我选择从 eMMC 引导。 以前、我们的主板使用 SD 卡引导、重启工作正常。 目前、当我们过渡到 eMMC 引导以进行大规模生产时、我们遇到了这个问题。

    尊敬的 Jason：

    从日志中、看门狗计时器似乎没有停止、这可能会阻止重新启动。

    Linux 应用程序是否使用看门狗计时器？ 或者这是系统的 WTD 之一吗？

    谢谢、

    我没有使用看门狗、从 SD 卡引导进行测试后、我运行了 reboot 命令。 打印日志仍显示监视程序错误、但系统可以正常重新启动。日志如下所示

    我想知道这是否与重新引导后的引导模式选择有关？

    尊敬的 Jason：

    eMMC RSTN 引脚连接到电路板上的什么位置？

    在 AM62Ax SK EVM 上、它连接到 SoC RESETz 引脚、以便在 Linux（重新）引导时、SoC 复位信号也会复位 eMMC、以便 ROM 可以重新初始化 eMMC。

    您好、

    检查后、我发现 RESETSTATz 确实未连接到 eMMC RSTN 引脚。 但是、即使我们通过跳线将这两个信号连接在一起、系统仍然无法正常重新启动。

    尊敬的 Bin：

    我们尝试在修改后的电路板（使用飞线）上手动触发 eMMC 的 RSTN 引脚、并观察到它在重新启动期间确实拉至低电平。

    我尝试了从 AM62Ax SK EVM 上的 eMMC 引导。 将 tisdk-tiny-image-am62axx-evm.rootfs.tar.xz 刷写到 eMMC 后、我发现系统仍然无法正确重新启动。

    这是日志

    尊敬的 Jason：

    您是否会在重新启动 eMMC 上的超小型 rootfs 时看到 eMMC RSTn 引脚是否变为低电平？

    您是否计划在项目中使用超小型 rootfs？ （我想几年前，我在 eMMC 上使用了超小型 rootfs、它没有重新启动、但来自 SDK 的其他 rootfs 没有这个问题。）

    嗨、Bin

    我们还可以检测 EVM 上的 RSTN 引脚被拉低。

    我们当前的工程涉及使用 gstreamer 等库扩展超小型 rootfs、以运行我们的应用。 重新启动故障可能是由于超小型 rootfs 中缺少组件而导致的吗？

    尊敬的 Jason：

    让我在使用微型 rootfs 的 EVM 上重现问题并对其进行调试、以了解它为什么不会重新启动。

    我的队列中还有一些其他工作、可能需要一些时间来调查这个问题、可能会在下周晚些时候开始。

    Jason 大家好、很抱歉、我还没有机会进行调试。 如果我有任何进展、我会继续向您发布内容。

    您好 Jason：

    我可以在 AM62A SKEVM 板上发现相同的行为。 我想您使用命令#shutdown -h 现在 AM62A EVM 板挂起在下图是正常行为。

    #shutdown -h 现在表示关闭 AM62A EVM 板电源。 但 EVM 板不会关闭第一个 12V-5V 至 3.3V 电源。 您可以在下面找到 UART 日志。

    #reboot 表示软件热复位 AM62A、因此 EVM 板将再次重新启动。

    下面是我的验证结果、您可以仔细检查一下。

    此致！

    Han Tao

    我使用 AM62A Linux RDK10.1 进行验证。 (https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-D37Ls3JjkT/10.01.00.05/ti-processor-sdk-linux-edgeai-am62a-evm-10_01_00_05-Linux-x86-Install.bin)

    1. 在默认文件系统和微型文件系统中使用 (#reboot ) 命令。  

      通过 SD 卡引导 EVM 板经过 15 个圆圈的测试。 AM62A 现在可以成功重新启动。

    1.  在默认文件系统和微型文件系统中使用 (#shutdown -h now ) 命令。

      EVM 将在 shut.png 模式下停止。

    Hi  Han Tao

    您是否可以使用 tisdk-tiny-image-am62axx-evm.rootfs.tar.xz 执行正常的重新启动？ 我们在 EVM 上使用 SPL、使用此文件系统时、无法正确重新启动。 您能与我们分享您的刷写程序吗？

    您好 Jason：

    如果您需要遵循 Bin&Anshu 建议烧录 eMMC 使能热复位功能。

    我使用了 EVM 板、也可以试一下。 不刻录此位时、默认文件系统和微型文件系统无法重新启动。 当我刻录该位时、使用#reboot 命令 AM62A EVM 板可以成功从 eMMC 重新启动。 在微型文件系统上测试了 5 个圆圈。 请勿关闭外部 5V 电源、5 个圆圈全部可重新进入 Linux 系统。 请在您这边尝试。

    此致！

    Han Tao

    这是一次在 Uboot 上刻录 eMMC 复位功能位命令。  

    => MMC rst-Function 0 1.

    Hi Han Tao：

    非常感谢。 我会尝试一下、希望能为您提供有关星期五的反馈意见。

    Hi Han Tao：

     在 uboot 中输入 mmc rst-function 0 1 后、我的 EVM 通常可以重新启动。

    我们 在重启期间比较 RESETSTATz 的信号、最终确定电路板的 RSTN 引脚连接存在问题。 正确连接它并输入命令“mmc rst-function 0 1“后、reboot 命令现在可以正常运行。

    感谢大家在本主题中提供的支持和帮助。
