ESP32-S3FH4R2 串口打印一直乱码

[tony5555]

自己画的电路使用ESP32-S3FH4R2芯片，使用D:\SoftwareInstall\esp-idf\examples\get-started\hello_world这个列程烧录到ESP32-S3FH4R2的芯片后波特率115200串口打印打印一直为乱码，同样的代码烧录到安信可的的NodeMCU ESP-S3-12K-Kit开发版波特率115200能正常的打印字符没有乱码，ESP32-S3FH4R2使用普通UART串口打印非CDC模式麻烦帮忙看一下，修改原理图请见附件

使用波特率7300就能正常的打印字符了，但是代码中我设置的是115200的波特率的进行编译的，同样的固件刷入NodeMCU ESP-S3-12K-Kit开发版波特率115200能正常的打印字符没有乱码，而刷入同样的固件我画的ESP32-S3FH4R2开发版就需要设置波特率7300才能正常的打印字符
