相同的映像一直在启动、直到我们执行安全启动、现在内核出现恐慌并停止启动。 请查看引导日志并告诉我出现了什么问题。

尊敬的 Dharmik：
日志指示内核中 ADC probe/init 的问题。
1/。 是否是在 HS-SE 上引导的日志？
2/。 从 FS 引导时是否未观察到问题？
３。 是否在 TI 电路板或客户电路板上进行测试？
此致、
- Hong

Hong Hong：

1/。 是的

2/。 是的、它在 HS-SE 上引导。

３。 它是客户电路板。

如果需要我方面的更多信息、请告诉我。

另一方面、如果我在 dts 文件中禁用&tscadc0 节点、则会出现以下错误：

谢谢、

尊敬的 Dharmik：

2/。 从 HS-MCU 引导时是否未观察到问题 FS？

我们是否在客户电路板的 HS-Linux 上顺利引导 FS 内核？
此致、
- Hong

Hong Hong：

抱歉、更正了拼写错误。 是的、内核在 FS 上启动时 没有出现任何问题。

谢谢、

达尔米克

尊敬的 Dharmik：
您是否会将工作案例 (HS-SE) 和非工作案例 (FS) 的完整引导日志附加到客户电路板上。
此致、
- Hong

工作日志：

e2e.ti.com/.../success_2D00_boot_2D00_log.txt

将 FS 转换为 HS-SE +不工作日志：

e2e.ti.com/.../failed_2D00_boot_2D00_log.txt

谢谢、

达尔米克

尊敬的 Dharmik：
我将连接我在 HS-SE 上捕获的工作引导日志并在 TI AM62L-SK 电路板上连接 AM62L Linux SDK 11.2.8.2。
我们可以在您的设置中使用最新的 AM62L Linux SDK 11.2.8.2 进行测试吗？
此致、
- Hong

尊敬的 Dharmik：
我们目前遇到了将文件作为附件上传至 e2e 论坛的问题。
我刚刚通过电子邮件向您发送了工作日志文件。
我们在 e2e 论坛上继续讨论。
此致、
- Hong

在最新版本中、我已在 u-boot 中修改 dts 以启用看门狗、但无法获得输出  => WDT 列表 命令。 如前所述、我使用的是 11.00.15.05 版本。

DTS 更改：

&main_rti0 {
       status = "okay";
};

默认配置：

+CONFIG_WATCHDOG=y
+CONFIG_WATCHDOG_TIMEOUT_MSECS=60000
+CONFIG_CMD_WDT=y
+CONFIG_WATCHDOG_AUTOSTART=y

除了这些更改、您能否确认如何在最新版本的 u-boot 中启用看门狗？

谢谢、
