Hi everyone, I am trying to bring up the DP83867 with RGMII on the STM32MP131DAG7. However I am getting the following error:[ 18.253959] stm32-dwmac 5800a000.ethernet end0: renamed from eth0 [ 23.695184] stm32-dwmac 5800a000.ethernet end0: Regist...
I am trying to decrease the DDR Clock Frequency for STM32MP257F-DK board. I used STM32CubeMX Tool to change clock tree and generate the modified device trees and made the required changes, compiled and flashed, but still the ddr clock remains the sam...
Hi Team,We are planning to use STM32MP235A for an IP PTZ camera application. Do we have an example code for the same? If yes, kindly share the links to relevant resources.Thanks,Preethi
Hi everyone,I have the STM32MP257F-DK development kit and I'm interested in flashing or building Android OS for it. So far, I've found some resources and guides for the STM32MP257F-EV1, but nothing specifically for the DK variant.From what I understa...
... in order to make a "Hello World" and be able to use it for more applications? Based on the steps of the ST wiki on the stm32mp257f-dk through a VirtualBox to be able to use Linux and configure the A35, we realized that when performing the last st...
I am running OPTEE OS 4.0 from openstlinux distro 6.0. When i build package optee-examples (I also tried to build examples manually) and try to run it I get the following error; D/TC:? 1 tee_ta_init_pseudo_ta_session:303 Lookup pseudo TA 8aaaf200-245...
I am trying to build a custom Yocto Scarthgap image for a custom STM32MP153CAA3 board.I have followed the guide at https://wiki.st.com/stm32mpu/index.php/How_to_create_your_own_machine but have several issues.I have created a configuration in CubeMX ...
Hi I have a board based on a STM32MP135F. I can see that CLK signal of my sdcard (SDMMC1) very look like a 50 MHz sinusoidal instead of a clock. I have tested with and without my 22 Ohm resistor on this line and I am now looking into the device-tree/...
I created a layer using bitbake-layers create-layer --priority 7 ../layers/meta-st/meta-my-custo-layer and created mkdir recipes-graphics/wayland/weston-init/ and created folder called files and append file weston-init_%.bbappend and in files i add...
Hello everyone,i'm working on a custom SOC based on ST32MP135 and LAN8710 ethernet phy chip.When the HAL_ETH_Init() code runs and sends the module reset by setting the ETH_DMAMR_SWR bit, the loop exits with the HAL_ETH_ERROR_TIMEOUT.The current inter...
