WhyCan Forum(哇酷开发者社区)

1、使用 tina sdk，天嵌的 核心板
2、使用uart3 控制台输出
3、改了根据自己的底板改了 dts之后，时不时的卡死。有时候修改个 无关的 dts（比如加一个不存在的 i2c cpt 触摸 节点竟然好了）。修改无关的 dts 时好时坏。
4、把uart3整个 dts节点全部 屏蔽掉，竟然能正常 启动并且输出，好像一直用 earlyprink输出的。
5、有时候死机日志 也不一定固定在哪一行，老是感觉 启动时候初始化不知道怎么了，测了很多次，感觉都不是本质问题，感觉像 修改dts节点 或者 串口啥的 影响了启动顺序导致死机。

实在找不到问题了，各位大佬有遇见类似的现象的吗 救救我
