自己画的K230PCB 参考嘉立创庐山派，上电后0.8，1.1，1.8，3.3，5.0v电压与时序都没有问题，但是发现插入usb0后电脑并没有反应，观察uart0的输出，有一次抓到了输出boot failed with code 19，但是只看到过一次，接下来的所有重新上电均无输出，还有什么调试的方法吗，今天观察到引脚F12与F7未连接，前者为VDD0P8_CORE,后者为AVDD1P8_CODEC,这对于测试的话会有影响吗，上电后k230主控有略微发热，然后0v8对地阻值未10欧姆左右，这个是否正常
定制版
OTP未成功烧录
boot failed with code 19 是单板进入了烧录模式，请问，有没有烧录单板对应的软件？请在不掉电情况下反复的按RST按键重启，看是否每次都打印boot failed with code 19？ 还有请测试24M晶体是否正常。
没有烧录单板对应的软件，因为usb连接没有反应，所以没有烧录成功任何东西，
不掉电情况下反复的按RST按键重启，基本上都不会打印boot failed with code 19，之前打印似乎是偶然的。
24M晶体正常起震，示波器图片我添加一下

重新进入usb烧录模式之后，尝试通过burning tool来烧入img到sd卡报错和日志为
