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"...
Hi all,I own an STM32MP157-DK1. I am trying to setup the TFT display ILI9341 on this discovery kit. I am familiar with Bitbake and Yocto. Are there any minimal images available that I can bake and dump on my discovery kit (SD card) to test my display...
Hi!I've been running an embedded linux (built with Buildroot) on a STM32MP157F-DK2. I need to use both USART3 and UART7 ports to interact with other devices.I've used it flawlessly with only USART3 enabled in linux's device tree for months. Recently,...
Hello,Searched around but couldn't find a similar issue.Please point me to one if one exist. I have a custom board with the stm32mp157c mounted. Board works fine, trying to communication between the m4 and a7 processor using the rpmsg devices. I have...
