hi, I have been working on compiling an openstlinux image with yocto, when compiling the image with bitbake it does not show me any error, but when mounting the image on the SD card it shows me the error that it cannot find "uInitrd", check in the ...
Hi all,What is the most correct and easiest way to generate dtb for the STM32MP1?I tried following this : https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Developer_PackageLooks way complicated and I get below error :/opt/st/...
Hello,I try to make a simple PWM work on PD15 with TIM4_PWM4, wich normally output the PWM on D6, the 6th pin of CN14. I followed example of https://wiki.st.com/stm32mpu/wiki/PWM_overview as I only need two PWM controlled with sysfs (the first beeing...
I am using STM32MP157C and as part of the project i am trying to configure the hardware by enabling and disabling certain security features(tamper detection,trust zones,rd and wr protection etc)I would like to know if there is a way to access the sys...
HI all,Is it possible to just compile the kernel in yocto environment for stm32mp1 using command : bitbake -C compile virtual/kernelThis command is currently failing with below error message : If not this , then what is the correct way to do it?I hav...
I'm using a SoM with a STM32MP157C. I've connected a LTE modem to uart7, its connected with a 4-wire uart, going trough a level shifter. The device tree contains the following:uart7_pins_mx: uart7_mx-0 { pins1 { pinmux = <STM32_PINMUX('E', 7, AF...
as the pictures shows，I use stm32mp157c borad to driver the raspberrypi,7inch-touchscree .when the systen run on,i used "modetest" command to list panel on system,I can see panel,but the connector and crtc is null,I can't understander the reason . a...
I am using a custom.board with STM32MP157C.I am not able to connect to it via JLink EDU.It shows that the ST device could not be verified.Also tried using the STM32Cube ide as well as JLink commander.Facing same issue.What should I give in the device...
Hi,I have installated postgresql on STM32MP1.I would like to install libpqxx , a C++ based postgresql connector. How can i do that? FYI: apt-cache search returns empty.
Hi,I want to interface WM8960 with STM32MP1 using I2S interface. I initialized the WM8960 driver and added the DT entry in device tree file but the drivers fails.Can you please share some pointers on how to interface audio codec with I2S to STM32MP1 ...
