Hello ST, We are trying to enable USART6 as a serial console, in the stm32mp257f-dk board, we have builded the SDK using Openstlinux "Distribution package", I had done the below changes in the stm32mp257f-dk.dts device tree present in the kernel...
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...
I'm trying to debug TF-A BL2 on my stm32mp157f-dk2 kit 1. Memory card is setup. Partition 1&2 is copied with TF-A2. I'm expecting that if I connect a debugger, open a debug session with open OCD and gdb , I would be able to connect to the target3. I...
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...
Hello everyone,I am reaching out to the community regarding an issue my team is experiencing on the STM32MP257F, specifically within a project running on the Cortex-M33 core.ContextWe are attempting to configure SPI2 to transmit data to an external D...
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...
Hello, I am currently having problems initializing the I2C interfaces on the M33 core of the STM32MP257F-DK Board. The interfaces in question are I2C2 and I2C8, the ones exposed on the 40 pin connector. I have code that toggles LEDs and it works fine...
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...
