Tool/software:
Background: The project uses the AM625 chip, the SDK baseline is 10.01, and encountering garbled code issues when configuring the serial port baud rate
The local code modifications are as follows:
Set the baud rate to 921600. The serial port print screenshot from the A53 core is as follows. The red box indicates several seconds of missing print information, still at the baud rate of 115200. How should I modify it to ensure the entire board startup process uses 921600?
Reset the baud rate of the serial port tool to 115200. The missing print information in the red box above is as follows:
