Hello,I have made a custom STM32MP133D board and I am in the process of building the custom bring up. The bringup uses discrete regulators and not a pmic. I have followed the process of building the device tree for the TF-A and build the TF-A .stm32 ...
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 ...
Hello,I am using STM32H735 and installed a Bluetooth module STM32WB05N.For the STM32WB05N, it is configured as a transparent mode running as HOST + CONTROLLER firmware. I got the firmware from this github: STM32WB05N Firmware.I have modified STM32WB...
Hello engineers, I'm using the latest version of CubeMX and creating a project with STM32MP135FAFx, but the highest clock configuration I can select is 650MHz. According to the datasheet, the maximum supported clock is 1GHz. Someone else has raised t...
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...
