I've been working on this for a few days now, I can't seem to get the DAC to work with the DMA. I can get the DMA to work with ADC easily, I can use the DAC without DMA easily, but the DAC doesn't feel like working with the DMA. I set up the DMA to w...
I'm trying to get PySide6 and some common Python packages on my STM32MP257. "apt-get install python3-PySide6" doesn't work. I also tried to install the PySide6 package using pip3, which installed successfully, but gave me the error "ImportError: libX...
Hi, I'm new of linux.Now I have two network interface on my board, end0 for ethernet & en1u2i4 for 4G modem.The ethenet(end0) is directly connected to my PC only for development that I can use ssh to connect my board.And I want the other connection t...
Hello. Could someone clarify for me where this message is coming from and how can I fix it?stm32_etzpc bus@5c007000: rng@54003000 not allowed on bus (-13)Is it OP-TEE or U-Boot miss-configuration?I'm trying to patch openstlinux-6.6 OP-TEE and U-Boot ...
Hi,I am working on optimizing the boot process on my STM32MP157DAC board by removing U-Boot and booting the Linux kernel directly. I’ve been following the documented procedure from ST for the STM32MP1 series:ST Wiki - How to optimize the boot timeTF-...
Hi everyone,I'm attempting to optimize the boot process on my STM32MP157F-DK2 board by removing U-Boot and booting the Linux kernel directly via the FIP. I've followed the documented steps for STM32MP1:TF-A BL2 Modifications:Updated STM32MP_BL33_BASE...
I've been playing with the STM32MP257-DK, first looking at the start package. I have now delved further with the developer package, and ran into issues while following the README.HOW_TO.txt that is found in the linux kernel directory. I followed the ...
Hi there, I am working with the STM32MP135F-DK microprocessor and have already designed the user interface in Figma. Now, I would like to move forward with developing this UI. Which tool should I use to implement the UI on the STM32MP135F-DK? If I ch...
Dear ST Community,We are working with the STM32MP257F-EV1 evaluation board and using the Yocto Distribution Package for our software stack.Our intended boot sequence is:Boot starts from the Cortex-M33 core.The M33 firmware is responsible for triggeri...
Hello, I'm working on PTP synchronization using the STM32MP257F-DK development board, and I'm encountering an issue with generating a PPS output on a GPIO pin. I'm using Buildroot as the build system, configured with the Bootlin external tree availab...
