STM32 MPUs

Hi,I use stm32mp157a-dk1 board and sdcard boot.Host PC is win10, virtualbox and ubuntu 20.04.1​I try this example but have some problem.​https://github.com/STMicroelectronics/meta-st-stm32mp/blob/dunfell/recipes-kernel/linux/linux-stm32mp/README.HOW_TO.txt​I don`t have folder "/media/$USER/bootfs/" and media/$USER/rootfs/lib/modules/​My board complete this step.​But error occurs this command . /media/sh/bootfs/ is not directory. (*'sh' is my user name) What is problem? ^^;;

Hello STM Community,I am following the workshop STM32Cube.AI workshop with my STM32MP157C-EV1 https://www.youtube.com/watch?v=k8AAr84z27s&list=PLnMKNibPkDnEOUdTXlDH7yWN6qyxXPsEb&index=9&t=8m15s When I analyze the model I get the error "Required Ram or Flash size for asc is bigger than available Ram or Flash�? (where >asc< is the name of my model), with resources required for the model: “Flash occupation: 15.90 KiB�? and “RAM: 20.64 KiB (128.00 KiB present)�?. So the RAM is not the problem. I get the feeling, that it has no allocated Flash. How do I declare which Flash storage to use? In the advanced settings, I can set “use external Flash�?, but I do not get how to use it and if I have to use it. Is there any good tutorial?I tried different Networks, like the HAR-CNN-Keras from the 'getting started', but that is an even bigger Network.Tried the STM32MP157C-EV1 in engineering boot mode (B 0 0 1) and boot from microsd (B 1 0 1)Used Software: 1.Windows 10 using STM32Cube

Hello all,   I managed to enter the DFU mode by rebooting the SoC from the command line after setting the proper tamper register to get the Uboot to select my desired USB boot mode. After flashing the new image with the STM32CubeProgrammer I would like to be able to reboot the SoC again without having to do press physically the reset button or have to type the reset command inthe Uboot with a STLink console.   I see in the wiki that the proper configuration of the tsv file should be able to trigger a RESET PhaseID (0xFF) but I have no clue on how to do it. I entered the line "-      0xFF   reset  Binary none   0x0    arm-trusted-firmware/tf-a-stm32mp157c-demo-logic-analyser-mx-serialboot.stm32" at the end of my tsv file but it does not do the trick. By checking the stm32prog.c source code it seems that that PhaseID is unusable and will only be triggered in case of an error ocurring

We are using STM32MP157c-DK2 board. Using STM32MP_KeyGen_CLI tool generated public key, private key and publicKeyhash.bin. As mentioned in STM32 webpage, https://wiki.st.com/stm32mpu/wiki/KeyGen_tool Hash public key contains the SHA-256 hash of the public key in binary format which generated by Gen tool.Is there a way or steps to generate same publicKeyhash.bin (without using STM32 key_Gen tool) via openssl or any other crypto utility

Also is there any working tutorial regarding this discovery kit​

Hi everyone,I have a problem using STM32CubeProgrammer (and CLI). They are both showing that my userfs partition have a size of -1162381824 bytes. That partition have size of 2.9GB. After programming with CubeProgrammer I have kernel panic, and I don't know if this is related to CubeProgrammer. I'm trying to program SD card partition by partition using STM32CubeProgrammer but I don't have luck. When I get whole RAW image of SD card and then flash another SD card everything is working. When I get bootfs, userfs, vendorfs and rootfs using dd comand from SD card and then try to program using CubeProgrammer, kernel panic happens. Where I am wrong?Best regards,Nenad

Hello,I use STM32MP157C-DK2 with the last open st linux distribution (20-11-12). I try to enbale CAN network on microcontroller but I can't send message.I m sure of my code on microcontroller side because it's work fine with an other distribution.I change dts and dtsi file to enable can pin mapping but without success .What can I try ?

Hi,Is there a way to set the QSPI clock on the MP157 to be free running while also using the QSPI? The programming manual mentions that free running mode will prevent the QSPI from being usable.I am working on a project to interface the MP157 to an FPGA via QSPI, however, having the clock start up only when the transaction is active prevents the QSPI clock from being able to drive an IO PLL. If it were free running when no transaction was active, then the FPGA could maintain a synchronous PLL lock on the MP157.

We have product built around STM32MP1157C and boots up with GPT partition table. However, we would like to boot it up with DOS (MBR based) Partition table. As per the documentation - section 4.3 of https://wiki.st.com/stm32mpu/wiki/STM32MP15_ROM_code_overview, it seems GPT is not mandatory for STM32 ROM code to locate FSBL. So, accordingly, I dumped u-boot-spl.stm32-mp1som-pxl7-basic at LBA 34 (at offset 17K), but it fails to boot up.Any help in this regard is highly appreciated.Thanks,Pradeep

the microcontroller receives a total of 4 bytes of data every 50 µs via SPI.  each Two bytes form a value,  which is represented as a float with 16 bits. how can i join two bytes into a 16-bit float?float v_beta_d_star = 0.0f;float v_beta_q_star = 0.0f;float v_beta_d_star = (spi_values[0] << 8) | (spi_values[0] & 0xFF);float v_beta_d_star = (spi_values[1] << 8) | (spi_values[1] & 0xFF);

​I created a very simple module and placed it in /lib/modules/4.19.94/kernel/drivers.And do depmod -ae.​And I confirmed that probe is possible with modprobe <driver name>.I expected this driver to load automatically after a reboot, but it didn't.This driver and device tree have the same compatible node.This can be confirmed by the fact that the port declared in devicetree is being operated correctly by modprobe.Could you tell me what is likely to be wrong?​My device tree   foo_peripheral_pins: foo_peripheral-0 {      pins1 {         pinmux = <STM32_PINMUX('F', 2, GPIO)>;         output-high;      };   };   foo_peripheral {      compatible = "factory,fooperipheral";      status = "okay";      pi

I'm having trouble setting up a hdmi monitor with a usb touchscreen on the stm32mp157. In the command lsusb it appears, but I can't link it with X11. What is the correct process for configuring the USB touchscreen on this board? I managed to make it work on a raspberry pi4.

I am working on the STM32MP157A. Setting PLL in the STM32CubeIDE does not work as expected. 24 MHz HSE DIVM4 = /5 DIVN4 = X84 DIVQ4 = /5 should = 80,460,000 . The MX program says 80,960,039. I do not understand. If the MX program is right, then what is the equation? I am trying to find the right combination to exactly get 460800 baud to work. The numbers I used should have worked.
