Hi,we are currently developing our own board using the STM32MP151 MPU.Currently i am working on the FSBL in the non secure mode using U-boot.I am able to generate a device tree with CubeMX, compile U-Boot and download it via STM32 Cube Programmer ove...
We are using a STM32MP157A-DK1 and try to reduce power consumption.1) When A7 and M4 are running we measure around 300mA.2) When A7 is in Suspend-To-Mem and the M4 is still running we measure around 80mA.3) When the M4 also enters standby mode the po...
Hi i want to display splash screen on HDMI monitor instead of DSI monitor of STM32MP157C-DK2. I know that it has something to do with U-Boot configuration, but i can't find right options to enable this feature. I would be grateful if somebody could h...
I am currently working on a design based around the STM32MP157C (mounted in the Seeed SoM - STM32MP157C).I am trying to connect to the M4 Core on the target but I cannot halt it. When I attempt to do it, the debugger can halt the A7 CPU0 but fails at...
It's so hard to start my audio project. I am stucked at sai clock settings
Hi all,Windows 10 IoT Core already supports run on the single ARM Cortex-A7 MPU! Is there a BSP of the STM32 MPU that can be used for the Windows 10 IoT?Refer here:https://docs.microsoft.com/en-us/windows/iot-core/learn-about-hardware/socsandcustombo...
The kernel I used was 4.19 and the CPU on STM32MP157AAA3 was able to read the CPU at 650M frequency.I failed to read when I only replaced THE CPU with STM32MP157DAA1.STM32MP157AAA3 To read the CPU frequency results are as follows:STM32MP157DAA1 Reads...
I want to exchange large data buffers with the coprocessorI have tried following wiki page.https://wiki.st.com/stm32mpu-ecosystem-v1/wiki/How_to_exchange_large_data_buffers_with_the_coprocessor_-_principle#User_space_interfaceI tried to bitbake, bu...
hi, I need to stop some peripherals within m4 core before linux stop command:echo -n stop > /sys/class/remoteproc/remoteproc0/statehow can I manage that ?tnx.
