Is it possible to make this system using stm32mp157??

inkong · ‎2024-05-30

Hello,

I would like to make the system below using stm32mp157.

- System Description -

1. 100Mbps Full-Duplex Ethernet

2. Cortex-A7 receives and transmits data from Ethernet on the PC.

3. Cortex-A7 calculates Ethernet data and sends the result to Cortex-M4.

4. Cortex-M4 controls peripheral(SPI, I2C, UART, GPIO) using DMA and interrupt

Can I implement a program like the above??

I've usually used F4 series or L4 series, so I don't know about MPU lines.

If the program is implementable, please let me know what I need to know.

If the program cannot be implemented, please recommend MCU or method that can be implemented.

Hi @inkong,

I think that the system that you described is possible with the STM32MP157 lines.

As you said that you “don’t know about MPU lines”, I could suggest that you have a look at the STM32 MPU wiki (https://wiki.st.com/stm32mpu/wiki/Main_Page), if you don’t know it yet.

The following articles might be interesting for you:

https://wiki.st.com/stm32mpu/wiki/STM32MP15_microprocessor to get an overview (block diagram) of the STM32MP15 microprocessor and to retrieve the list of internal peripherals that are available.
https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards to start with any STM32MP1 development board.
https://wiki.st.com/stm32mpu/wiki/ETH_internal_peripheral and https://wiki.st.com/stm32mpu/wiki/Ethernet_overview as entry points for the Ethernet connection.
https://wiki.st.com/stm32mpu/wiki/Exchanging_buffers_with_the_coprocessor and https://wiki.st.com/stm32mpu/wiki/How_to_exchange_data_buffers_with_the_coprocessor about communication between the Arm® Cortex®-A and Cortex®-M cores.
https://wiki.st.com/stm32mpu/wiki/STM32CubeMX (software configuration tool) and https://wiki.st.com/stm32mpu/wiki/STM32MP15_peripherals_overview to get the possible assignments of the internal peripherals (SPI, I2C, UART, GPIO…) .

Hope this information helps.

Regards,

JC.
