Hi there,in order to have an externally generated clock for our LTDC peripheral we decided to use the I2S_CKIN as the reference clock for PLL4 on our customized STM32MP157CAC board. Reference manual and STM32CubeMX are showing that this opportunity e...
Hi,I have a problem with the configuration of PA10 of stm32mp135 to work as pwm of TIM1_CH3. I also make an experiment to disable completely timer and PWM and I also can't control this pin using gpioset. In the documentation I saw that this pin is de...
Hello everyone! I'm using the STM32MP157F-DK2 and the OpenSTlinux Distribution package with a set of Yocto recipes that do not affect the Linux kernel. I have written a program for the Cortex-M4 core and created a device tree in CubeMX. Then, I built...
I'm building libqmi for the STM32MP157 and getting an error at this point in the build GISCAN Qmi-1.0.girTraceback (most recent call last):File "/home/ed/STM32MPU_workspace/STM32MP1-Ecosystem-v4.1.0/Developer-Package/SDK/sysroots/cortexa7t2hf-neon-v...
Hi,I have a slight problem with st-image-weston.bbappend.In my meta-layer in folder /recipes-st/images/ I add an st-image-weston.bbappend to install a few packages I intend to have.And now something is strange, after adding a new package to install i...
Hello,I am working on a project that is using wifi to communicate with the connected device and the latency is critical. We are using the wifi JODY-W263-00B from U-Blox connected by SDIO bus, and for measuring the latency we simply use ping command. ...
Hi I have used the "bitbake -c populate_sdk st-image-weston" command to generate an updated SDK with OpenCV and ZerMQ packages. The SDK is generated successfully.The issue is when I want to use this SDK in STM32CubeIDE, since I can't seem to find the...
Hi all,We design the custom board use ST32MP157 base on the design of STM32MP157-DK2 kit. We use the SD card for booting. The image and device tree is custom base on example of STM32MP157-DK2 kit. The board has a issue when booting via SD card. This ...
Hello, For some time I testing STM32MP135f with 1GHz CPU clocking. I was able to generate optee OpenStLinux but I see a lack of CPU efficiency. I'm curious what is the difference in efficiency between trust and optee. If I use the trusted option the ...
We are trying to bringup the Wi-Fi module connected over the sdmmc3 line with the STM32MP157F based custom board. But it seems, when enabling the sdmmc3 lines on the kernel and u-boot dts files, the kernel boot fails on "Waiting for Keymaster device"...
