Ask questions and find answers on STM32 microprocessors, including hardware, power, DRAM, flashing, interfacing, device tree, and peripherals.
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 ...
Hello,I would like to ask you few questions since I have some unclearances about STM32MP157F MPU:1. If 933MHz DDR3L RAM was connected to the MPU according to the schematic, will the MPU automatically underclock it to max 533MHz?2. Is it possible to c...
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.
