Hi everyone,I'm new to using MPUs.For an application, I need to transfer data from the SRAM (data obtained with the M4) to a DDR buffer in order to communicate with the A7. I based my application on the example here : How to exchange large data buffe...
Hi,I have a firmware doing permanent acquisition and processing of a signal coming from SPI on the M4 side - consider it an audio stream.On-demand I would like to save the processed buffer (say ~10 consecutive buffers once in a while, e.g. 1s every 1...
Hello STM-Team,I am working with STM32MP157F-Eval board. The SD card and NAND booting are working fine. But, getting issues while booting with eMMC.I have tried a workaround which seems to be working and I want to make sure if it is the right way of ...
Hi,I want to play a video from mounted USB stick. Once USB plugged the host, I mount it with "mount /dev/sda1 /mnt" and than quit the psplash screen with "psplash-drm-quit" on target. After that, trying to play a video with "gst-launch-1.0 playbin ur...
Hi,We want to use a KSZ8851SNL SPI ethernet phy as second eth interface on a custom board. The implementation was according to https://www.kernel.org/doc/Documentation/devicetree/bindings/net/micrel%2Cks8851.yamlThe eth0 interface is initialised with...
Hi AllI have disabled the second core to validate one of old product, which runs on single core,and same application cpu usage i have seen is 90-95 %and same application runs and does the same spi transaction, i am seeing the cpu usage is 57%all cons...
I want to use part of the SRAM3 shared memory for data transfer between the A7 cores and the M4 core. On the A7 core I used mmap on /dev/mem to remap the sram to user space and copy the data to/from the SRAM3 buffers. The result is however not stable...
Hello STM-Team,We are developing a custom board based on STM32MP157C-Eval board.In that, we are planning to have MLC NAND Part number #MT29F16G08CBACAWP:C instead of SLC NAND.For Software point of view, I want to understand that if the existing NAND ...
Is it possible to use AI frameworks like ONNX and / or Openvino (and related accelerators like movidius, GPU) on STM32MP1? I took a look but I found only examples with tensorflow lite and Coral devices (i.e. https://github.com/STMicroelectronics/meta...
Hi,My evaluation kit is stm32mp157c-ev1, I can flash code to eMMC or SD via STM32CubeProgrammer successfully, and it can work expectedly.We need to running program on eMMC without SD card. Flash the eMMC code via STM32CubeProgrammer is very slow and ...
