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...
When porting applications from single core M4's equipped with FLASH, the RAM associated with M4 in MP1 is supposed to cater for both RAM and former FLASH needs. It won't fit. How to overcome this if M4 code/data size cannot be reduced?
Hello,I am in process of designing my own STM32MP1 powered device. I was wondering if I can use STLINK-V3MODS as a drop in replacement for ST-LINK/V2-1 in STM32MP157-EVAL reference design. I need the Virtual COM interface embedded in device.-Mark
I want to emulate the stm32mp157 on qemu. I have been taking the kernel image and initrd from yocto build, but it is not loading the kernel. using the following commandqemu-system-arm \-M virt -smp 8,sockets=1,cores=4,threads=2 -m 4G \-cpu cortex-a7 ...
Recently I got a problem with RPMSG driver when M5 coprocessor restarts. Thanks to https://community.st.com/s/question/0D53W00000936uRSAQ/kernel-panic-with-pollselect-syscalls-on-virtual-uart-devices-to-m4-core-when-m4-watchdog-restarts?t=16321442601...
I am working on yocto project. I started with a custom board based on stm32mp157. You can find the board description in this link custom board. Vendor has a board support package in dunfell version. But I am doing my project in kirkstone version. I h...
Hi,I'm having some difficulty routing 1GB DDR3L memory with the STM32MP151DAC1. Both reference boards available for this product use different memory or pitch configurations. I found an Application Note, AN5122, that guides through memory routing, bu...
Hi,I find the 'STM32MP1_SeriesDDRmemory_routing_guidelines_layout_examples_V3.0' from ST's site.I've several questions: It seems the column 'STM32MP15XXAA LENGTH (mm)' is the package delay per pin, right?Actually, the delay is a time factor. But here...
Hi,Are there any references for configuring the I2S supply voltages in device trees for STM32MP135-DK.From the I2S module currently we are getting the output level as 5V, is that expected or is there any way to change that from 5V to 3.3V.
Hi,After reading the document I understand the interrupts are handled by pin#, and we set GPIOsel within EXTI_ConfigTypeDef.My question is how do we determine which port generates the interrupt?Suppose I use PA0 and PB0, and I only want to use one ca...
