Hi all, I am using stm32mp157f-dk2 with ecosystem 3.1.During development, I need to update the device tree and kernel config very often.My current approach is to do bitbake -c cleansstate <image> bitbake virtual/kernel -c menuconfig bitbake <image>Ho...
Hello , Currently, i am working on STM32MP157. I am trying to change the device tree USB type C configuration into a USB type A host.I've disabled usbotg option under stm32mp1571.dtsi file. I would like to know where i could add USB A host configura...
I am writing an application for STM32MP157F MPU which required TCP and UDP sockets. Is there any example?
CPU: STM32mp153CACProblem: CPU is unable to boot further because of error:"ERROR: Node system_off_soc_mode not found"I have temporarily commented out the panic in the TF-A This allows us to boot further into u-boot and then linux. But I'm worried th...
Hello, I am looking for the right documentation for creating a custom poject using stm32mpu M4 cortex but using the peripheral connected to 40 pin header and not the Arduino connector.please let me know and also the limitation if any if i connect an ...
Hi all, I am studying the pmic of stm32mp157f-dk2.My ultimate goal is to write a device tree structure for other pmic chip like tps65 series to replace the stpmic&i2c4{ ... stusb1600@28{ compatible = "st,stusb1600"; reg = <0...
I have a STM32MP157F-DK2 board.I have installed the distribution package from the tutorials from st.com. I want to install the lxml package which seems to need the libxml2 and libxslt development packages as dependencies, but these packages are not a...
This is an STM32MP157c based board design with Micrel KSZ9021GN PHY in 100 MII mode. Have you ever seen this situation before? Here are the relevant parts of the boot, the early kernel part looks normal and the LEDs are on.... [ 2.507568] stm32-dw...
Hello,I am having difficulties initializing the USB OTG in the ST Ecosystem 3.1.0 with the STM32MP157C in the Octavo OSD32MP15x SiP. With the ST Ecosystem 2.1.0 there was no issue and the previous image still works on my development board. I only nee...
Hello every one I am starting with the STM32MP157, and i wonder if there is a schematis that i can follow that doesn't require the use of external DRAM or any IC meaning without (linux) using bare meatal code through the IDE. just to operate the ADC ...
