Hi there, we are developing a custom STM32MP135 board to run openstlinux on it. It will be our first experience with embedded linux (linux) systems, so we have some tasks that we don't know if it can be done. These tasks are the following:Can we acce...
Hello,I am currently using the MOOC hands-on lab examples to understand how to use inter processor communication between the A7 and M4. The lab is using the STM32MP157C-DK2 board, whereas I am using the STM32MP157F-DK2 board. Currently, I made a new ...
Hello everyone,I am currently working on a project involving the STM32MP microprocessor and I've been exploring the Real-Time Clock (RTC) functionality in the Linux kernel for timekeeping purposes.From what I've gathered so far, the datasheet (RM0441...
Hello We are using STM32MP157 in our custom board. We are trying to trigger Cortex-M4 from Cortex - A7 BareMetal software. In this we generated cortex-M4 code in CubeMX and debugging with ST32CubeIDE and in debug it's working fine. ...
I am currently flashing a custom mickledore distro on a STM32MP151CAA3T and after the fsbl1 i get this error : ERROR: DDR addr bus test: can't access memory @ 0xc0000004 PANIC at PC : 0x2ffdf9d9 Can someone explain how to solve this issue?
First acquaintance with STM32mp157FDK2. A couple of weeks ago I bought two sets to try. In a week I figured out how to put together my image with Yocto. And today what was supposed to happen happened. I connected the KIT to the power supply with PD3....
I am a 100% new to the stm32mp1 series. I have been working with the stm32f3 most recently.I need help with direction on where should I start, down to the selected hardware. (not sure if stm32mp1 is even the right choice)So here is what at trying to ...
I know this is probably a really *** question but how do I actually use the data I send from the A4 to the M7 of the STM32MP1 chips? I ran the examples that are clearly setup to send messages from the M4 to the A7 via the virtual UART, which are the...
Hi, I have a STM32MP157F-DK2 with a firmware running with remoteproc and using remoteproc and rpmsg drivers to communicate with userspace through ttyRPMSG0, created at firmware init with libmetal and openAMP libraries. After multiple days of research...
Hi,I have a current project using the M7 that I need to port over to the A7. The goal is to be running bare-metal code on the A7, like we are on the M7. Currently, I am following this open source guide to run bare-metal on the A7 and it seems to work...
