Hi,I am in the process of migrating my application to OpenSTLinux 6.1 (Scarthgap) and we are targeting a boot time of ≤10 seconds. while working on this, I observed that the OP-TEE layer takes some extra time during secondary CPU initialization. As ...
I've followed the build instructions for the STM32MP distribution package 6.6.116 and managed to build the boot sd card for MP135F-DK and that works fine.When i build for MP257F-EV1 board, the build works fine and the boot sd card appears ok, but dur...
Hello! I am using STM32MP257F-EV1 board. I have issues building CM0PLUS_DEMO. I am trying to build it in STM32CubeIDE v2.1.1. I have error:Drivers/STM32MP2xx_HAL_Driver/subdir.mk:43: *** unable to generate command line.I applied recommendation mentio...
I notice that, since scarthgap, the meta-st-stm32mp layer has been fixed on Linux kernel 6.6. Are there any plans for a newer kernel release for "wrynose"?
I wonder how I can enable ETH Clock Output for my Realtek RTL8211F Ethernet PHY. Right now, the crystal for RTL8211F won't start and I don't know why. I'm guessing that it's an unstable crystal. Anyway! To enable the ETH Clock Output for my Ethernet ...
Hi everyone,I am working on the STM32MP257-EVAL board, where my Cortex-M33 application requires both FreeRTOS and OpenAMP middleware to run together.After referring to the STM32CubeMPU packages, I found separate example projects:One for FreeRTOSOne f...
HelloI am using STM32CubeMX (ver 6.14.1) to create a Device Tree (DT) for a custom board based on the STM32MP255F-AK.I tried to uncheck the “Secure” option for RIF -> RISUP -> LTDC_CMN in STM32CubeMX, butthe checkbox is grayed out and I cannot make t...
I’m working on an STM32MP257FAK3 custom board using Yocto/OpenSTLinux and trying to get SPI1 working as 3 wire SPI via the spidev interface. My device tree configures SPI1 pins and enables spidev@0 at 1MHz, 10MHz and 500KHz. (see DTS fragment below)....
Hi there! I am trying to interface a Sony IMX335 5MP USB Camera Module with the STM32MP257F-EV1 Development Board using the OpenST Linux. On trying to do so, the STLink USB Port sends random ASCII Value while booting, significantly increasing the boo...
HelloI am building Linux on a custom board using the STM32MP255F-AK.The following error occurs during kernel boot:[ 15.371350] stm32-dwmac 482c0000.eth1: Failed to reset the DMA [ 15.386447] stm32-dwmac 482c0000.eth1 end0: stmmac_hw_setup: DMA engine...
