The serial port is your eyes in embedded debugging. On the JL Jieli AC696N chip, I've set up UART0 to print logs at 1M baud (configurable to any pin) – logs fly without stuttering.

Full configuration steps and code snippets are in the article. If you're working on audio products with AC696N, this workflow will save you hours.
