Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
Hello, we are going to develop an application which requires the usage of a cortex-m core that communicates through ethernet.Both the wiki and the migration guide (AN5253) from cortex-m4 to MP1 says this is not possibile. Is it really true? Looking a...
Has anyone used OPENAMP in their projects without HAL? I usually do not use HAL in my projects. IDE SW4STM32 for Linux. with thanksAlexander
I want to exchange data between M4(running custom firmware) and A7(running OpenSTLinux) by using the Linux RPMsg framework.The ST-wiki refers to https://www.kernel.org/doc/Documentation/remoteproc.txt.I tried to run the example given by kernel.org, b...
Can I use STM32MP1 without an operating system?Linux is harder for me to master than a microcontroller.It would be convenient if the cube generated code hal for the processorIs there a similar feature planned?If not, is there a step-by-step instructi...
I made linux configuration by virtualbox. and I did copy to board kernel file by ssh(scp command). now I am testing M4 firmware .https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157C-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-M4/M...
I need to develop M4 and how do I configure system resources,for example,we need to configure uart on M4,the modification as follows,but it doesn't work:&m4_rproc { m4_system_resources { status = "okay"; }; }; &m4_uart3{ sta...
Hello,Sorry for the easy question but I am facing an issue while connecting STM32MP1 to wifi. I have followed steps 1 to 3 (reference link). At the end of step 3, I can connect my STM32MP1 device from remote machine using the following command:ssh ro...
I'm using STM32MP157A-EV1.It configured boot from eMMC mode.This is because SDIO is used as interface.I inserted the uSD card into the slot for trial.The information of SDIO is as follows.root@stm32mp1:~# cat /sys/kernel/debug/mmc0/iosclock: 9900...
Hi all! Can anybody give advice about other methods of working with interconnect between MPU and MCU. I saw example working with RPMsg, but in this case we have a problem with memory, because we need a big buff in MCU for data. Now we trying to use D...
I want to build image with appliance of build development and network features? I cant understand the process. Where can I find a manual for yocto and stm?
