I use a STM32MP157C and connected to MAX24287 PHY by RGMII.After linux booted there is only 100Mbps connection - I put the PHY into Diagnostic Loopback Mode and the situation is the same.My dts:ðernet0{ pinctrl-names = "default", "sleep"; pinctrl-...
How can I configure the i2c duty cycle to 50% in the linux device tree for a 33kHz device?I have modified the frequency from 100000 to 33000 but I couldn't find a setting for the duty cycle and right now I measure ~83%.MPU stm32mp153.
Hello there,We are working on a design based on the STM32MP1 eval kit which is using Realtek RTL8211 for Ethernet.However this IC seems to be hard to buy; Realtek distributors are giving lead times of +1 year.Can someone recommend alternatives?Thanks...
We are trying to bring-up our custom board and every step of the way we see panic messages, we need some direction in understanding what went wrong. Our board has the following:Processor: STM32MP157FACxQSPI NAND flash memory is our boot device (AS5F1...
From my understanding of the documentation, my steps to lowest power (VBAT mode) on the STM32MP1-DK2 kit would be: Connect Battery to VBATSet BREN in TF-ADisable wake sources other than from PMIC and RTCenter sleep via: "echo mem > /sys/power/state"I...
I've just finished the tutorials on MP1 and have built a few Nucleo projects. When I want to use a GPIO pin on the Nucleo board I go o the ioc file, name a pin and hit Project > Generate Code, and I'll see the pins at the bottom of my Core > main.c ...

Hi,Is there any Yocto layer which can be added to ST's Linux distribution to connect smartphones such as Android Auto/Apple CarPlay? Thanks in advance.
hi,we are trying to flash our yocto build on our custom board using the stm32cubeprogrammer via usb in dfu mode. the flashing fails w/ the following message:19:33:39 : Opening and parsing file: tf-a-stm32mp157f-nff-mx-usb.stm3219:33:39 : File ...
