Hello. Every one.I've been designing using STM32MP151 series.Now, i just have changed the package from STM32MP151CAB3(0.8pitch) to STM32MP151CAD3(0.5pitch).And then, the current is consumed more than 0.4W.of course, the power pin count is fewer than ...
Hi!I have made a simple computer with STM32MP151AAC3 processor.I have modify so I can boot either from UART4 or eMMC. My question is:When I want to flash OpenSTLinux onto the eMMC, can that be done via ST-Link and STM32CubeIDE? Just like regular STM3...
I see the following when I try to download the latest or select any other version of the tool
I had an error while building the image. I didn’t try to figure out why and why it was necessary to turn off the network. I just removed the entire function. After that everything build together.https://github.com/karu2003/stm32mp1_note openembedded-...
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....
