The STM32MP157 is configured for ADC acquisition within the M4 core, and the ADC data is carried using the DMA method. It turns out that the sample rate and the sampled data are correct when debugging with the development board MCU start-up method Debug,

The two graphs above are the data obtained from different cores. The left side is the MCU method start, the sampling rate is 1.6M, the acquisition of 1KHz signal, the acquisition of 1600 points is correct; the right side is the EMMC from the A7 core ...
