Hi,
- When you hit the error, will you see nvidia logo? According to your log, bootloader says the cable is not connected. Are you sure you have cable connected?
[0002.172] E> tegrabl_display_init_regulator: hdmi cable is not connected
- Also, the log is hard to read. I see something as below from your log. Please try to get it readable first.

I do not connect a cable, but this have no influence about the module boot , I just find the module state by the Uart log.
sometimes the xavier can enter the login screen, then there will still be some log messages below. Please help to analyze the possible reasons？

I do not connect a HDMI cable ， I find the Xavier state just by the Uart log. I think the operation will not influence module boot.
After the login screen appears, the following log will still appear ，this is not normal ，please help analysis possible reason， thanks.
As long as the normal power supply guaranteed, the module output should be normal, right?

你好，
- 我试过了，同一个模组放到另一个载板上后log就是正常没有乱码中文的，如附加。基本上可以确定不是模组故障引起的。
- 载板实际测量模组的供电没有问题， 模组在启动过程中还可能从载板上读那些信息呢？ 什么原因导致出现log乱码呢？载板和开发板的载板设计基本相同，接口都有预留，载板上有个eeprom，暂时不知道作用。
- 我怀疑是载板699pin连接器有接触不好的问题，但是利用万用表测了连接器的通路并没有发现短（断）路的情况。
现在我们手里有两块板子都是有类似问题：一开始正常，用了几天时间后，显示先出现不稳定的现象，之后就直接没有输出了。
但是不清楚是什么原因导致的？帮忙给些建议，因为不清楚从载板上什么地方分析起。
