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...
Hello! I am developing a custom board based on STM32MP151C MPU (TFBGA 361pins) with a RMII Ethernet PHY, and I have a simple question regarding to the PHY interrupt signal -sorry if this is a duplicated question, I haven't found a related topic in th...
Hello,we have product based on a STM32MP157 running Linux. The distribution is based on Yocto kirkstone and we are using a 6.1.82 Kernel. For the MP1s' GPU we use the open source entaviv driver that ships with this kernel. The device has a graphical ...
Hi there, I'm trying to integrate in my linux distribution (custom board based on STM32MP153) a LTE Modem (uBlox Lena R8) which is controllable via USB. At the powerup is see that the device tries to enable the USB (it should bring up 8 virtual COM/t...
I'm trying to run QT examples on a build created using st-example-image-qt (Ecosystem v2.1) on our custom board. We have a simple RGB display 800x480 resolution, so I modified the cursor.json on the board as follows{ "device": "/dev/dri/card0", "outp...
Hello,I am using a STM32MP157C development board from Myirtech and trying to interface the board with a CAN device.I am able to bring up the can0 interface. It can send data, I can see it from oscilloscope over Can Hi and Lo pins. The dmesg output is...
