Hello. I am currently working on a custom stm32mp157a Linux based board with a KSZ9896 as network switch. At this point everything works on the board expect the RGMII connection to the switch. The RGMII is currently running in 100MBit mode for easier...
When booting off SPI NOR I would expect the device (an ST32MP151D) to possibly check the device ID then read a block starting from 0. Where is this fully documented ? What I actually see is two pairs of negative pulses on nCS then it floats open ci...
I'm working on a project using the Seeed Studio STM32MP157C-Odyssey-SoM (it is a module with the STM32MP1, DDR, eMMC and STPMIC). I am making a new PCB into which the module is plugged. When using the module on the original host board from Seeed, b...
Hello,I am working with an STM32MP157 -DK2The Distribution Package currently offers a Yocto version that is aligned with Dunfell (in particular meta-st-linux)Is this repository maintained somewhere in a way that it is aligned with current Yocto relea...
I have the following pinctrl entry in my 5.10 device tree to use the USART1 and the serial port fails, due to an incorrect pin configuration for PZ7 AF7.usart1_pins_c: usart1-2 { pins1 { pinmux = <STM32_PINMUX(...
