I want to implement the program that exchange large data with each other on Cortex-A7 and Cortex-M4 by using DDR.Thanks to following wiki page, I have understand the mechanism that exchange large data from Cortex-M4 to Cortex-A7 by using DDR.https...
Hi,Can I access APB5 bus in engineering mode to run I2C4 with I2C4_SCL = PZ4, I2C4_SCL = PZ5?
Following the instructions found in en.FLASH-stm32mp1-openstlinux-5-4-dunfell-mp1-20-06-24.tar.xz and using create_sdcard_from_flashlayout.sh to write the data to an SD card did not work for me. When I inserted the card on the stm32mp157c-dk2 dev bo...
Is there a way to directly start M4 and run M4 firmware from BootRom.I am aware of the Engineering mode, however it requires the help of a debugger to copy the M4 firmware into the memory and run it. I like to do the same but in stand alone mode.I am...
I am evaluating some embedded software libraries which are available for multiple ARM Cortex M3/M4 MCUs from ST. I would like to evaluate what would be the porting effort to port these libraries to the embedded M4 core in the STM32MP1.What is the clo...
EDIT December 2020 : all issues and limitations mentioned in this article are fixed and integrated in latest Ecosystem V2.1Hi Community members, MP1 fans, Given significant number of posts we received from the delivery of Ecosystem V2.0 in July thi...
hey, which profiler I can use for my custom board (without x11)?
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...
