现尝试自编译的tina，在boot0和uboot阶段都有输出，内核没有。
采用awboot的方式引导主线内核的方式，在boot阶段也有输出，内核没有。
尝试使用芒果派的mq-r-t113-rtl8189fs-5113-dns-uart0.img，在boot0和uboot阶段也都有输出。
所以我判断是因为硬件问题导致内核无法启动。

正常设置的设备树，但是引脚没有复用成i2s，而是变成了io_disabled

从这里可以看出2034000.daudio current state: sleep，状态是sleep。

自制的t113开发板，使用的是百问网的sdk，现在是boot0和uboot都有输出，但是在内核阶段没有输出，不知道是内核没有启动，还是使用的串口错误。
求大佬解惑，这个问题已经找了好几天了。
