电源问题引起的系统无限重启问题
板子型号
X3-PI
现象分析
- 开发板在系统启动时特别是在手动reboot时会发生无限重启问题。
- uboot正常启动，但是加载到kernel后开始重新启动。
- 官方给出的回复是供电导致的，这个没有问题，通过更换更好得电源可以解决。
- 但是在后续实际项目中发现，同批次板子还是会有一些设备会发生此现象，所以个人感觉，不仅仅是供电问题，应该是在x3pi的硬件电源部分缺少一颗稍大的滤波电容，未能减少设备侧电源波动导致的。
解决办法
- 因为无法更改硬件，但是通过测量扩展引脚处的5V引脚与Type-C是走同一路，所以在扩展引脚处增加一颗电容，我增加的是一颗16v/470uf，至此设备启动完全正常了。-
