STM32 MPUs

I tried downloading the 2.0 SDK but the link goes to the "sources" tarball., not the SDK. I tried to get there various ways but can't find the download.Thanks,Andrew

If windows is not supported, then it is not stated in previous steps. If it is supported, then path is missing at step 2.1 /Peter

Hi All,I'm coding last from 6 years for embedded system projects. I have good knowledge in bare metal programming. I want learn Linux and device driver implementation using Linux.Please suggest me a board, with which I can start my Linux learning journey. Thanks,Basava

Hi, I have an STM32MP157C-DK2 reference board and it is booting with yocto linux.From the bootlog I came to know that reset reason is checked in the Primary Bootloader by reading a register from the file tf-a-stm32mp/plat/st/stm32mp1/bl2_plat_setup.c uint32_t rstsr = mmio_read_32(stm32mp_rcc_base() + RCC_MP_RSTSCLRR);   Now I want to know the reason in the uboot level before lauching the kenel image to add an extra environmental variable in uboot.I tried to read the register using readl(),_raw_readl() API's but I was throwing data abort error while booting and the board gets reboot.So I need help w.r.t the way to read register or any other way to get the reset reason information.RegardsSrikanth.

To bootup STM32MP157 from SD card, the layout for SD is partition#1, u-boot-spl.stm32, first copy of first stage bootloader partition#2, u-boot-spl.stm32, second copy of first stage bootloader partition#3, u-boot.img, second stage bootloader partition#4, rfs.ext4, root file system   here there is single copy of second stage bootloader, if there is power off during flashing firmware, uboot on partition#3 might be corrupted and then my device would not be able to bootup, I would like to change the partition layout to partition#1, u-boot-spl.stm32, first copy of first stage bootloader partition#2, u-boot-spl.stm32, second copy of first stage bootloader partition#3, u-boot.img, first copy of second stage bootloader partition#4, u-boot.img, second copy of second stage bootloader partition#5, rfs.ext4, root file system   and modify the spl first stage bootloader to add in check, if it detect 1st copy of uboot is corrupted, then it will load second copy instead, so far haven't seen

Hi,i try to use a ADM DMA with the board in object.I generate the code with CUBE MX and i add only the function HAL_ADC_Start_DMA(&hadc1, (uint32_t*)&buff, 1); before the while loop in the main.After i start the ADC, the hadc1.State remains in HAL_ADC_STATE_REG_BUSY and the DMA2_Stream0_IRQHandler never happens.I attach the .ioc file of the project.Someone can help me?Thanks a lot

Hello,I am working on a project that acquires ADC readings and saves them into a buffer in the M4 side of STM32mp157 chip on DK2 board, now I need to build a kernel module that copies the saved buffer from the SRAM to DDR on the A7 side when a certain interrupt is triggered.As I am a beginner in embedded linux world I am wondering about the way to do this, I tried memcpy() at first but errors arise when inserting the module (Can't page virtual address error), I also tried converting the SRAM address from physical to virtual before memcpy() but that didn't work as well.Is there a direct way to copy data between the memories like memcpy() or do I need to use DMA from the kernel module to copy the data, if the DMA is the way, sharing an example would be great.Thanks

I use STM32MP151CAA3 mounted on my own board.I want to start to count up TIM3 in PWM generation mode in Cortex-M4.​I have written following code, However, ​TIM3 doesn't start to count up (After Line 56, TIM3_CNT value doesn't change at all).In this code, PB04 port is used as PWM output port.​void TIM3_Count_Start(void) { TIM_HandleTypeDef m_handleTim3; TIM_OC_InitTypeDef sConfigOC; TIM_SlaveConfigTypeDef sSlaveConfig; TIM_MasterConfigTypeDef sMasterConfig; GPIO_InitTypeDef GPIO_InitStruct;   /* Peripheral clock enable */ __TIM3_CLK_ENABLE(); GPIO_InitStruct.Pin = GPIO_PIN_4; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_LOW; GPIO_InitStruct.Alternate = GPIO_AF2_TIM3; HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);   m_handleTim3.Instance = TIM3; m_handleTim3.Init.Prescaler = 0; m_handleTim3.Init.CounterMode = TIM_COUNTERMODE_UP; m_handleTim3.Init.Period = 0; m_handleTim3.Init.ClockDivision = TIM_

Hi：I would like to ask what is the maximum EMMC capacity supported by stm32mp157A chip.Can you give me some advice.eg:128g

I'd like to use aiohttp on OpenSTLinux but when I try to install it complains about needing Python 3.6+.Is there a straightforward way to upgrade to a new Python? I'm running the STM32MP1 DK2 board.Thanks,Andrew

I designing a developer board with an stm32 MPU. This board have an HDMI port for transfer the audio and video signal from the board to the TV. Which IC can I use for convert video signal( MIPI/DSI ) and audio signal (I2s) to HDMI ?

Dear STM engineers and community,I'm working with STM32MP157-DK2 (Developer-Package 1.2) and an evaluation board for ADAU1977 ADC from Analog Devices. Desired setup entails using the external codec as the master of I2S communication (the same as with the onboard Cirrus codec on the board).Following the great documentation provided by the wiki pages (kudos to the teams working on that!) I have almost managed to get everything working perfectly.In order to get to this point I have done the following:Desoldered SB1 through SB4, and then soldered SB13 through SB16 in order to disconnect onboard codec from SAI2 and access it from the GPIO headerAdded the codec_of_xlate_dai_id in the source of the manufacturers driver according to: https://wiki.st.com/stm32mpu/wiki/SAI_device_tree_configurationIncluded the source files of the edited codec driver through kconfing and menuconfig and configured them as modularEdited the device tree (stm32mp157c-dk1.dts) according to all available documentation

Hi,I'm testing the UART_Receive_Transmit_Console example from STM32Cube_FW_MP1_V1.2.0 on the STM32MP1-DK1 discovery board. An HAL_ERROR is raised during the HAL_UART_Init and it seems that the function UART_SetConfig cannot find or set the clocksource correctly. I have set the PCLK1 clock in the u-boot and tf-a .dts files and I'm using a linux image with this setting.Is this function UART_SetConfig from the stm32mp1xx_hal_uart.c file only working in engineering mode or should it work also in normal mode?François

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.

Dear ST community,I’m trying to use the distribution package as described in the guide https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package#Installing_the_OpenSTLinux_distribution, but the oe-init-build-env file is absent.The first commands:$ repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-20-02-19And$ repo syncFinish successfully.However when I initialize the OpenEmbedded build environment (chapter 5.1):PC $> DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.shThe command fails due to the missing of the oe-init-build-env file.I check the revision of the openembedded-core folder and it is cd7cf933b3235560ec71576d8f3836dff736a39f as indicated in the manifest (https://github.com/STMicroelectronics/oe-manifest/blob/thud/default.xml), however inside the openembedded-core folder there is no oe-init-build-env file.How can I solve this problem?.Thanks in advance for any suggestions.Regards

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​​
