RFI regarding BGA package pin delays for the DDR3 and the EMMC interfaces

Hello,We are designing a custom board with the "STM32MP157FAC1" MPU.Would it be possible to get the die to BGA package pin delays for the DDR3 and the EMMC interfaces ?The AN5122 seems to only have track lengths. Our PCB track layout has some constra...

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 ...

DMA from SRAM to SRAM hanging in the M4 core

Hi everybody,I have generated an STM32 project via the STM32CubeIDE and modified the large example buffer (the firmware logic analyzer part), trying to substitute to the timer generated DMA transfer a second stream from SRAM to SRAM.In the next futu...
