I use STM32MP151CAA3 mounted on my own board.I want to generate TIM5 global interrupt in Cortex-M4.​I have written following code, However, ​TIM5 global interrupt doesn't occurs (TIM5_IRQHandler doesn't be called).In Keil MDK-ARM Debbuger, I have confirmed following settings are reflected.​--TIM5_DIER->UIE = 1--TIM5_CR1->CEN = 1​--When TIM5 CNT reach TIM5_ARR value, TIM5_SR->UIF is set.​#include "stm32mp1xx_hal.h"   void TIM5_Start(void) { TIM_HandleTypeDef m_handleTim5; TIM_ClockConfigTypeDef sClockSourceConfig; TIM_MasterConfigTypeDef sMasterConfig;   __HAL_RCC_TIM5_CLK_ENABLE();   m_handleTim5.Instance = TIM5; m_handleTim5.Init.Prescaler = 41999; m_handleTim5.Init.CounterMode = TIM_COUNTERMODE_UP; m_handleTim5.Init.Period = 0; m_handleTim5.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; HAL_TIM_Base_Init(&m_handleTim5);   sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNAL; HAL_TIM_ConfigClockSource(&m_handleTim5, &sClockSource

Following Wiki page shows how to flash TF-A , u-boot , root file system to SD card with STM32CubeProgrammer.​https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer#How_to_flash_with_STM32CubeProgrammer​In the above wiki page, I can flash ​TF-A , u-boot , root file system to SD card using USB.​Now, I want to flash ​images to SD card without using USB (directly from Host Linux PC).Is there any way to ​flash ​TF-A , u-boot , root file system to SD card without using USB with STM32CubeProgrammer?Best Regards.H. Masuda

Recently, I bought STM32MP1 DK2 board. Does DK2 board include NPU (Neural Processing Unit)? Can we use ​the NPU device via galcore.ko (Linux kernel module) to run deep learning network models on the DK2 board? Welcome to any hints and comments.​​BRs,Geunsik​​

I want to connect a SLC NAND to the FMC controller and boot from itWhat CS* must i use (NCE or NCE2) ?Why i got the "Pin not available for boot step" in CUBEmx when trying to select NCE2 ?

Hi all, I would like to know if someone is experiencing the same issue as me. I've got a custom STM32MP157CAC dev board and everything is working fine until I enable the HW crypto in the Linux Kernel and I want to mount a EXT4 FS. (EXT2 is ok but as no CRC/HASH checksum...)My Linux Kernel is based on v4.19-stm32mp branch from ST. The crypto HW accelration is working because I can run some OpenSSL test with cryptodev and AF_ALG. But I've got this issue when I try to mount a perfectly working EXT4 formatted USB Mass Storage: # mount /dev/sda1 /media/[ 391.163006] ------------[ cut here ]------------[ 391.166155] kernel BUG at fs/ext4/ext4.h:2038![ 391.170589] Internal error: Oops - BUG: 0 [#1] PREEMPT SMP ARM[ 391.176413] Modules linked in:[ 391.179463] CPU: 0 PID: 153 Comm: mount Not tainted 4.19.94 #1[ 391.185281] Hardware name: STM32 (Device Tree Support)[ 391.190428] PC is at ext4_superblock_csum+0x84/0x90[ 391.195289] LR is at ext4_fill_super+

Hi Guys,I just upgraded from STM32MP15-Ecosystem-v1.0.0  to STM32MP15-Ecosystem-v1.2.0 and having issues with several Qt libraries not included in the image “st-example-image-qt�?  (total of 35 missing out of 60). I have built this a couple times from scratch and no luck. All of the missing are included in the v1.0.0 revision that I built previously.I have diffed the meta-qt5 layer configurations and recipes, plus the create_qt5.py and not seeing any significant differences that would cause this.Oddly, when I build the SDK, all of the missing libraries are included.Has anyone run into this issue, has anyone been successful?   I can sort this out for myself if others are not having this issue. Just want to know if it this is an already known problem.I have followed instructions from https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package#Creating_your_own_Linux_distributionHere’s a list of what is missing:ibQt53DAnimation.solibQt53DCore.solibQt

I am searching for the simplest way to do that, I think you ST engineers made this chip for this purpose so maybe there are intended ways to that Thanks in advance

STM32MP1Cube 1.1.0Case: unload /remove the module rpmsg_client_sample  check lsmod the module is not loaded.start the M4 with OpenAMP raw example 4. the rpmsg_client_sample  is automatically loaded.Questions:what is the mechanism behind how is this module loaded ? How prevent this and manual load rpmsg_client_sample  How to replace this module with a custom module to interact with the M4 code?

SDMMC is on the board, pinout of SD differs from Evaluation board by SDMMC1_D2 pin (PE6 instead of PC10). Using STM32Cube I generated dts files for u-boot and tf-a for new SD pinoutWhat should I do next?Best regards

Hi： we will debugging the uboot using GDB，but we can't get possible target configuration files for <board.cfg>，how can we get the file？thanks

Hi, I read more wiki pages and found below command to partition emmc on ubootsetenv emmc_part "name=ssbl,size=2MiB;name=bootfs,type=linux,bootable,size=64MiB;name=rootfs,type=linux,size=512" gpt write mmc 1 ${emmc_part}When my board start up and execute above commands. I use gdisk to saw some error message.gdisk -l /dev/mmcblk1 GPT fdisk (gdisk) version 1.0.1   Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header.   Warning! One or more CRCs don't match. You should repair the disk!   Partition table scan: MBR: protective BSD: not present APM: not present GPT: damaged   **************************************************************************** Caution: Found protective or hybrid MBR and corrupt GPT.

Hi: I plan to allocate can peripherals to m4, but I have a problem in calculating baud rate. How can I determine the baud rate after allocating to m4.

Hi, I have STM32MP157C-DK2 demo board and I have ported STM Linux Yocto into board. I have enable NTP in the bb layer and I am able to see the NTP is up. When I want to get the status using timedatectl status I am getting the following output Local time: Wed 2019-10-30 15:16:43 UTC           Universal time: Wed 2019-10-30 15:16:43 UTC                RTC time: Wed 2019-10-30 15:16:44               Time zone: n/a (UTC, +0000) System clock synchronized: yes              NTP service: active          RTC in local TZ: no Where we can find that NTP service is active but the time zone was not able to find. Defaultly it was taking UTC time zone.But I want to change the time zone to As

I can access it with the given tools, like bluetoothctl, but I cannot build that same tool, so that I can write my own code. It seems some header files or libraries are missed. Am I missing something?

I am using rpmsg and OpenAMP framework for ipcc implementaion.I am trying to send some data from Cortex M4 to Cortex A7. Data array consists of integers of type uint16. But this transaction is happening properly. But when i use uint8, data is transferred properly. My question is, Is there any limitation on the data type in buffers? How can i send data of bigger data type to A7? Please help.
