多次 reboot 测试后，系统会卡住

[feiniao08102]

1. 自制底板
2. 核心模组是 Jetson AGX Orin 64G
3. SDK 是 Jetpack6.2 36.4.3
4. 多次 reboot 测试后，系统会一直卡在 “A start job is running for”
   
   
   
   
   
5. agx-orin-debug-log.txt 是调试串口打印的日志信息
   agx-orin-debug-log.txt (485.7 KB)
6. syslog.txt 是 /var/log/syslog
   syslog.txt (1.7 MB)

Is this issue able to reproduce on NV devkit?

[feiniao08102]

1. NV devkit 做 reboot 测试，目前没复现到问题
2. 如何从现有的 log 来确定问题点？

[WayneWWW]

Are you still able to operate the UART console when this issue happened?

[feiniao08102]

当系统卡住时，调试串口无法输入。

[WayneWWW]

please remove peripherals (hardware or software) one by one from your board and see if making any difference.

1. 由于我们的自制底板是带有一个RTC芯片，dts 里 disabled 这个 RTC 芯片，reboot 测试经过一晚上测试没复现到问题。
2. 为什么外部的RTC芯片会影响到系统?

Hi,

We are not sure about the situation as we don’t have same items on our side to check.

Is there any extra driver for that RTC chip?

[feiniao08102]

RTC 芯片使用的驱动是 Linux_for_Tegra/source/kernel/kernel-jammy-src/drivers/rtc/rtc-pcf8563.c

[WayneWWW]

Could you disable that driver first and see if this software removal would prevent boot hang?

[feiniao08102]

把 RTC 的驱动编译进 Image，而不是 ko 的方式，目前测试一晚上reboot，没有复现到问题。
