Using STM32CubeIDE Version: 1.6.0 on Linux I am able to follow the wiki to import, build, load and modify the OpenAMP_tty_echo application example. However, when I follow the same steps to import the FreeRTOS_ThreadCreation_CM4 application the progr...
Hello. I am working on standby/wakeup using gpio pin in stm32mp1 custom board. Going to sleep works well using gpio-keys but I can't wakeup. What bothers me most is that interrupt responsible for waking up does not set "waleup" attribute although it ...
I find the kernel Panic when I mmap 16 shared memory regions.（4KB/memory）
Whether it's to minimize computational power, improve the device's output or keep the GUI from freezing or crashing, debugging embedded software can be a challenging and time-consuming step in the process of developing embedded devices.With a multitu...
We've created a bunch of sample touch screen apps in our Storyboard ST GUI builder software that you can download, and save to your hardware. In moments, you'll be able to visualize and interact with a fully-functional sample touch screen application...
Dear community,we got a problem booting from our eMMC (THGBMJG9C8LBAU8) memory and we cannot figure out how to solve it. The Silicon Revision seem to be "Z". Attached you can the the ping pong between MPU (STM32MP151A) and eMMC. The initialization se...
Hello,We want to transfer a project from STM32F7 to STM32MP157C ( cortex M4 side). To do that we need an external RAM (arround 20 Mbytes). Is there a way to map an external RAM on cortex M4 side with cubeMX ?Best regards,Arnaud
Hello! I have just discovered that kit I would like to use to develop a new testing system within the company where I am working. However, I have some questions about it:What kind of additional card could we use to apply 24V to the board's input (I h...
Hy i am using the usart3 from the STM32MP157A-DK1. i orientated myself on the USART driver (https://elixir.bootlin.com/linux/latest/source/drivers/tty/serial/stm32-usart.c).butwhen i want to initialize theport I get following error code “Rs453Network...
