The actual USART bit rate depends on the delays introduced by the external trace, the
external device, system clock (CCLK), and capacitive loading. Excluding delays
introduced by external device and PCB, the maximum supported bit rate for USART
master and slave synchronous modes is 24 Mbit/s
我是调用 board.c 里面的 Board_Debug_Init() 函数来对串口进行初始化的,只是把 board.h 中的 DEBUGBAUDRATE 改为 921600,然后初始化后无法正常使用~

可是 921600 还不到 1Mbit/s。
这段话是从哪里可以找到呢?
