Hi,I want to connect some shields/sensors to STM32MP157C-DK2. Some of the sensors will draw about 200mA. How much current can I draw from the 5V/3V3 pins on the GPIO expansion connectors? The STM32MP157C-DK2 is powered over USB-C 5V/3A. OpenSTLinux i...
When I run the openamp image through linux command prompt, the application working fine. The RPMSG devices is created successfully.But when I've tried to run it from uboot, it stuck at MX_OPENAMP_Init(). This should be ok because I assume linux isn't...
Hi, I has two custom boards. There are have same stm32mp157 ic and ddr. The difference is emmc flash, A's from micron and B is THGBMNG5D1LBAIL. Basic chain:The A and B are bootup success.Trusted chain(TF-A + U-Boot)The A is bootup success.The B is bo...
Hello everyone.I am introducing me on this world of multiprocessors, by the moment I only had worked with NUCLEO-F3 boards or similar.For my new research, I plan to purchase a SOM + Carrier board with the STM32MP157C microcontroller.My intention is t...
I used the i2c4 for sii9022 chip,but it always busy and don't response for hdmi plug in.
We have made a custom board with an STM32MP157CAD MPU, this board is very similar to the DK2. We have adapted an LCD driver to support our LCD screen, over the DSI interface. It works, both on the DK2 with our own LCD screen, and on our custom board ...
Hello,I am fairly new to Linux and am trying to drive a DSI display using the STM32MP15-DK2 (not the one that came with the board) and was looking for some direction. I have been reading through the documentation related to DSI such as the DSI Intern...
Hi Support Team,Please help me to get the answers for below questions.1) Does STM32MP1 support double framebuffer ?2) If it supports then how can we allocate memories for two framebuffer ?3) If not then how can we avoid tearing effects using one fram...
Hi,I would like to develop IoT solutions around STM32MP157C-DK2. What is the normal process to launch STM32MP157C based customized board as a IoT gateway. Do we need to go through any certifications?Thanks,Naveen
hello alli have a STM32MP157C-EV1, and I want to build an m4 core development and debugging environment in minimal "st-image-core".M4 firmware created using "STM32CudeIDE" can be debugged in "st-image-weston", but an error occurs in "st-image-core...
