Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
I have observed that on the STM32MP25 series running OpenSTLinux, the GPU OpenVX packages are correctly built and the *.so files are present in the rootfs. However, after the do_image step, these libraries are removed and are missing in the resultin...
hi team,I'm facing issue in enabling usart6 of the expansion connector of stm32mp257f-ev1, All i did was to enable the &usart6 via DT overlay, even tried disabling dmas, but no luck.I have attached the kernel log and also attached the RIFSC debug log...
Hello,I'm working with the STM32MP257F-DK using the Yocto Project, and I'm trying to enable I2C in my custom Device Tree.However, I’m facing an issue where the I2C controllers remain stuck because of power-domain pending states.Here is the relevant d...
I need som help about constructing a FlashLayout file for CubeProgrammer. I have a template of a FlashLayout for the STM32MP1 processor. #opt Id Name Type Device Offset Binary - 0x01 fsbl-boot Binary none 0x00000000 tf-a-usb.stm32 - 0x03 fip-boot...
Hi,i need to modify the default debug uart serial in device tree of all the boot components (including u-boot, tf-a, optee etc) in stm32mp257f-ev1. I saw that external-dt_%.bb is fetching git://github.com/STMicroelectronics/dt-stm32mp.git and also EX...
Hi,I was wondering if there's any guidance on the approximate timeline for rebasing OpenSTLinux from kernel 6.6 to kernel 6.12 (autumn 2024) or to kernel 6.15, 6.16, 6.17 or 6.18?I know that this is an enormous amount of work and a very complex task ...
Hi ST Team, First of all, I would like to thank you for your support on my previous project based on the STM32MP255D series, which has now successfully moved into production. First of all, I would like to thank you for your support on my previous pro...
Hi,I’m working on a custom board based on the STM32MP157DAC. U-Boot splash is enabled, psplash is enabled in the kernel, and we have custom display drivers in both U-Boot and Linux. The display initializes in U-Boot and shows the splash, but ~4–5 sec...
Hello.Is there any way to exclude some GPIOs from Linux, when I control them from M4 core and I don't want to give an ability to control them from Linux apps? I would like to exclude e.g. PG12. I tried this, which should be exactly for such use:&gpio...
Hi,I am trying to use USART6 on STM32MP257F-DK development board. I have enabled it in the device tree, recompiled it and I now can see the /dev/ttySTM1 node. The problem is, that sometimes, after reboot, any access to the USART (even changing its ba...
