Tool/software:
The chip we are using is a TDA4VE chip, and the version of the SDK used is ti-processor-sdk-linux-j721s2-evm-08_06_01_02. The data is transferred using UART, the baud rate is set to 921600, and the data length of each packet is 1024 bytes. There will be a situation where some of the data behind the received packets is all 00. In addition, we have also upgraded the version of the kernel to version 10_01, and the same situation will still occur, please support, the following is the UART signal and the received data packet of the oscilloscope.
