STM32 MPUs

Hi everyone,I am thinking about using STM32MP1 for a smart wearable device, like a smart watch to run some machine learning algorithm. is it possible? is the battery able to support MPU?Does anyone know any product already used STM32MP1? it would be great help for me.Thanks very muchJane

Hello,I tried to enable spread spectrum for PLL1 by adding a csg line to the TF-A DeviceTree:pll1:st,pll@0 { compatible = "st,stm32mp1-pll"; reg = <0>; cfg = < 1 49 0 1 1 PQR(1,0,0) >; csg = < 60 600 SSCG_MODE_CENTER_SPREAD >; };I tried several different settings including one without any csg configuration. Each measurement (spectrum analyzer + nerafield probe) shows the exact same spectrum.Are there any additional settings I need to apply?

Hi,on a custom board with a STM32MP153AABxx and a W63AH6NBV 1Gbit LPDDR3 memory I am failing to initialise the DDR properly. I made the required changes to the upstream u-boot device tree files, added support for UART8 debug console and some minor things and compiled the SPL. I enabled the DDR interactive console and loaded SPL to the MPU using STM32 cube programmer CLI. STPMIC1 is properly configured, 1V2 and 1V8 DDR power rails are present. So far, so good. Trying DDR tests one-by-one, all are failing.LPDDR3 is wired according to AN5031 (Rev 4), section 10.1.7. I tried ODT both grounded and connected to the MPU. Routing should be OK.In addition to this, I tried to use CubeMX DDR Test Suite. Having a running SPL I managed to connect to it. The tool correctly recognises the DDR as:Config name: LPDDR3 16bits 533000kHz DDR Size: 1 GBits DDR Frequency: 533.0MHzThen it stops cooperating with:Exception in thread "Thread-4843" java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds f

I just created a project in STMCubeIDE for STM32MP157A-DK1 and am trying to run MCU debugging in ENGINEERING MODE and PRODUCTION MODE. I use an ST-LINK wire and an Ethernet Over USB connection. SSH and the UART command line work well. In engineering mode, I get the hardware breakpoints error. In production mode, all breakpoints that are set to an infinite loop do not work...this is very strange. What did I miss?

HiWe are using stm32mp157a processor in our custom board.we have an 3 port Ethernet switch(KSZ9893RNXIA) with spi interface to processor.We enable Ethernet switch using spi.Read and write to switch is working properly.But we when we connect Ethernet cable to board we have set ipaddr and try to ping the pc in Uboot. But It is not pinging and it is showing phy_conncet() failed.We are configuring switch in rmii mode with 100mbps speed.Processor specific dtsi file :ethernet0: ethernet@5800a000 {                       compatible = "st,stm32mp1-dwmac", "snps,dwmac-4.20a";                       reg = <0x5800a000 0x2000>;                       reg-n

Hi,During the actual production of our stm32mp157c products we do intend to use the HSM flow.But for now I am simply trying to test the SSP flow with some debug (development) keys and without access to an HSM.I went over:https://www.st.com/resource/en/application_note/an5510-overview-of-the-secure-secret-provisioning-ssp-on-stm32mp1-series-stmicroelectronics.pdfandhttps://www.st.com/resource/en/user_manual/dm00403513-stm32-trusted-package-creator-tool-software-description-stmicroelectronics.pdfbut unfortunately there is not much information regarding the STM32_Programmer_CLI.exe "-ssp" command with "hsm" flag equal to "0" (HSM not used)only:"<license_path|slot=slotID>: path to the license file (if hsm=0)reader slot ID if HSM is used (if hsm=1)"I don't quite understand exactly what "license file" I need to provide the command.And also, if HSM is not used, how will the ST MPU decrypt the data file (OTP keys) ? I am assuming it is somehow related to this license file ? because in th

Hi STM-Team,We have the custom board based on the STM32MP157C-Eval board.In that, we are not able to access the eMMC from u-boot command prompt. Currently, we are booting from SD card and able to access it from u-boot command prompt.We are able to see the 2 mmc devices but not able to access eMMC on dev-1. Please see below logs:-----------------------------------------STM32MP> mmc listSTM32 SD/MMC: 1STM32 SD/MMC: 0 (SD)STM32MP> mmc dev 0switch to partitions #0, OKmmc0 is current deviceSTM32MP> mmc dev 1<No output from this command>-------------------------------------------But, with same configurations, we are able to access and create partitions of eMMC through fdisk command from filesystem command prompt.

I have the following pinctrl entry in my 5.10 device tree to use the USART1 and the serial port fails, due to an incorrect pin configuration for PZ7 AF7.usart1_pins_c: usart1-2 { pins1 { pinmux = <STM32_PINMUX('Z', 7, AF7)>, /* USART1_TX */ <STM32_PINMUX('A', 12, AF7)>; /* USART1_RTS */ bias-disable; drive-push-pull; slew-rate = <0>; }; pins2 { pinmux = <STM32_PINMUX('Z', 1, AF7)>, /* USART1_RX */ <STM32_PINMUX('A', 11, AF7)>; /* USART1_CTS_NSS */ bias-pull-up; }; };Does anybody know why this is happening?Does the PZ7 require any specific setup to be used as USART1_TX?Best regards,--Mike

Hi everyone, I am using stm32mp157f-dk2 with ecosystem 3.1.I want to configure the usb type C port(CN7) as serial port, and communicate with the host PC.This article helps me a lot. https://wiki.st.com/stm32mpu/wiki/USB_overview#How_to_configure_USB_Gadget_through_configfsI modified the usbotg-gadget-config.bb, the stm32_usbotg_eth_config.sh and create my own service, as attached.After that, I can successfully set up the device. I can see ttyGS0 show up in my device.However, when I connect it to the host, although the host is able to detect my device, it can't recognize my device.What am I missing?I suspect that it is the stlink causing the issue, as it occupy the ttyACM0 already and the host cannot create another tty corresponding to the GS0. I am not sure how will the host OS deal with this situation.Regards, Leung10/3 update: I found that my PC can't boot up when the device is connected. It scared me. I am still investigating why it is failing, but I think the stlink is not the root

Hi Nicolas L (ST Employee),I have read the past article that you provide sources and directives to allow building the Android 10 delivery for the STM32MP157C-DK2.Could you please send me the solution?I hope you will be able to reply to me.By the way, can you find out my email in any way?Thanks & Regards,Hiromichi,

I am trying to create a custom board that boots from SDcard if an SDcard is plugged in, however, if the SDcard is not plugged in I would like the board to boot from the NAND. I want to do this programmable without the boot switch.Is this possible? Is there a sample project somewhere or some documentation?

I'm working with the DevBoard from Myir MYD-YA-157C which has the stm32mp157 MPU. I'm trying to chech the i2c from the M4 in the Engineering mode and have a problem.When I tied the I2C_TwoBoards_ComIT, it works. At least it generates the I2C5_ER_IRQ.But when I move to the i2c2 or any other with pins that I have out, it doesn't work. Just doesn't do anything, doesn't send anyithng and doesn't generate an interrupt.It is a simple test without any other peripherial enabled.Could you help me what is wrong.static void MX_I2C2_Init(void) {   hi2c2.Instance = I2C2; hi2c2.Init.Timing = 0x00701837; hi2c2.Init.OwnAddress1 = 783; hi2c2.Init.AddressingMode = I2C_ADDRESSINGMODE_10BIT; hi2c2.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE; hi2c2.Init.OwnAddress2 = 0; hi2c2.Init.OwnAddress2Masks = I2C_OA2_NOMASK; hi2c2.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE; hi2c2.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE; if (HAL_I2C_Init(&hi2c2) != HAL_OK) { Error_Handler(); }

Hi all,I am using MPU ref. STM32MP153F, do you say me what is the time that elapsed between a tamper is detected and the backup resister are finishing erased?And the backup SRAM?Thank you in advance

Hi everyone!I want to use a hardware semaphore to access SRAM4 memory from both Linux and M4 firmware on STM32MP157A-DK1 board. There are no problems with the M4 firmware. But for Linux I have to create a driver. There is an example in this article: https://wiki.st.com/stm32mpu/wiki/Hardware_spinlock_overview But according to this example, I can't choose the number of the hardware semaphore that I want to use. I ask for advice on how best to organize what I want to do. Maybe I can use a hardware semaphore from user space?

HiWe are using stm32mp157a-dk1 board.We are writing code in bare metal.Its working fine when we run in SRAM.But when we jump to DRM its hanging.

The STM32MP157 demands a maximum time of 10 ms from reset command to boot partition data. According to JEDEC No 84-B51 the maximum time from reset command to the first data is up to 1 second (tBD):All data sheets of eMMCs that I found specify their boot timing according to the JEDEC spec. I don't understand how I can ensure that eMMC boot works reliable for all devices.in the field. Can you please help me?Do I understand it right or is there a solution available?

Hi,I want to make a bare-metal application (without Linux OS) on a STM32MP157C-DK2 Board.I need to use the usb host controller from this board (that why I choose it: multiples USB socket) but in the projects created with CubeIde, I can only assign USBH_HS1 or USB_OTG_HS with the A7 runtime context and my application C code is under the folder project_CM4 wich seem related to only M4 context and not with A7 context So, my question is simple: could we use a USB mass storage device with a bare-metal application on STM32MP157C-DK2 Board  without a Linux distrib?I am wondering because I can’t find either a HAL USB module as expected in the “stm32mp1xx_hal�?  list as if the only appropriate way to manage usb was with an OS attached to cortec A7Thanks in advance for any help

Are there any plans to support the STM32MP157F-DK2 board in mainline (vanilla) U-Boot?It's supported in the ST fork from U-Boot, but with an older version from U-Boot from the year 2020.Could also ask this in the U-Boot mailing list.

I am using a KSZ9021GN PHY in MII mode. Due to supply chain issues we had to resort to this PHY. (Cube MX says I can't use GMII mode). I am experiencing this apparently common issue: [ 15.650981] dwmac4_dma_reset err [ 15.652849] stm32-dwmac 5800a000.ethernet: Failed to reset the dma [ 15.659006] stm32-dwmac 5800a000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed [ 15.668518] stm32-dwmac 5800a000.ethernet eth0: stmmac_open: Hw setup failed I have read over https://wiki.st.com/stm32mpu/wiki/Ethernet_overview#How_to_debugand it says typically that the clock(s) are not present at reset, but I am not clear on what clocks are involved in MII mode. Any thoughts on what might be wrong?
