Hi,I'm just getting started with C programming for embedded Linux using the STM32MP13x. My applications are mostly IoT applications.I'd like to know which IDE is best for beginners, between STM32CubeIDE and Visual Studio Code.And where can I get info...
HelloWe are using the STM32MP257F in M33TDCID flavour using the packagestm32mp2-m33td-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11We can boot and run the Non Secure application, but when we try to use some of the peripherals (I2C, SPI, GPIO)we see p...
Hello,I am working with a SOM based on the STM32MP157C and I am trying to bring up a display panel that uses the Sitronix ST7703 MIPI DSI controller.The operating system has been built with Yocto using the BSP provided by the SOM vendor. This BSP is ...
Hello.We are developing a device with the STM32MP257 and we will not have a USB Type-C connector in our design. We plan to use the USB3DR as a USB2.0 device with a USB 2.0 connector to USB boot (USB boot for flashing). Does the STM32MP2 embedded boot...
On DK2, ADC is used to measure the voltage on cc lines, how to skipcan u give me the yocto steps to follow on commenting the following line in uBoot Device Tree:do u have to create a new layer or can we edit the patch file in the uboot device tree a...
"is there possibility we can auto mount a usb when connected to usb host and how to build the udev-extraconf package for my stm32mp157f-dk2" how to build this please give the steps to build for my stm32mp157f-dk2 as i want my pendrive to mount aut...
I have had difficulties programming the STM32MP257 via stm32cubeide. I followed the first few steps to flash an OS image onto the board using the section populate and boot the image, from the STM website. When trying to flash IOC generated code via s...
Dear All,I'm having problem to get DFU over USB running on custom board.In general device can boot from SD card and with no SD card it can be detected via uart4 by STM programmer, so it enters DFU as far as I can tell.USB DP/DM is connected to DP2 (b...
Hello Experts,Based on STM32MP257F-EV1 we have designed a custom board. For the DDR, PMIC, and eMMC we tried to follow the EV1 rooting as much as possible. There are few differences on the BOM though: Our DDR chips are Alliance Memory AS4C1G16D4A-62B...
Hello,I am testing a custom board based on STM32MP257FAK3 with two DDR4 MT40A1G16RC-062E_B devices, for a total of 4 GB (32-bit width).I have correctly set up the main configuration files to work with the PMIC and UART. I also exported the PCB layou...
