UART interrupt processing is completely implemented by the application itself: When the default UART interrupt processing flow cannot meet the application requirements, such as the UART of the application is implemented by a third-party code, you can use ‘bk_interrupt_Register(xx, isr, arg)’ re...

LOG 就是从 UART0 输出的。在 BOOT 程序里，把 UART0 映射到 IO1（RX0）和 IO3（TX0）上。
