Hi, we are developing a custom board based on the STM32MP157C. We would want to use several GPIOs for buttons. We have most of them working, but a couple GPIO pins do not yield input events to the Linux kernel. The problematic pins are PC1, PC2, and ...
Hello,I am currently using the DDR Utility in STM32CubeProgrammer to tune the DDR4 on my STM32MP257F-EV1 board.I would like to perform infinite read and write tests on DDR to check the stability over time.From the documentation, I found that there is...
Hello,on a stm32mp257f-ev1 board I'm developing a non secure M33 firmware using hpdma3.I configured hpdma3 on optee RIF DT to be used only by M33 (CID2) for all channels as follow&hpdma3 { st,protreg = < RIFPROT(RIF_HPDMA_CHANNEL(0), RIF_UNUSED, R...

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 ...
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...
