Regarding OpenStLinux (yocto) for stm32mp257f. Mickledore: everything works fine for our custom stm32mp257f board. Scarthgap: everything works except 3D graphics. When loading module etnaviv we get the following system hangup (optee panic): [ 13.1...
Hello,Whenever I build OpenSt-Linux with Yocto, or download the starter kit, I get several flashlayouts:In images/stm32mp2/flashlayout_st-image-weston:* extensible* fastboot* fastboot-opteemin* optee* opteeminI can make some supposition about: optee,...
Hello,Excuse me, has anyone had experience accelerating the Whisper-tiny model for speech-to-text tasks using the NPU on the STM32MP257-EV1 board? From my understanding, the process involves converting the PyTorch or TensorFlow Whisper model to Tenso...
I have been trying to port touchscreen with Stm32mp157c-dk2 without success. Actually, touchscreen has 15 pins but Stm32 has 20 pins and I handled the unmatched pins on Stm in logical way. Rest of the pins match but no screen seen. Do I have to make...
I have seen a lot of videos on YouTube where STM32N6 demonstrates incredible AI features such as multiple pose estimation, multiple object detection and multiple object classification at the same time.But I haven't seen anything similar for STM32MP25...
I am working on getting a new board design with a STM32MP153F to boot from parallel SLC NAND flash. The flash chip is 1 GB, using the FMC interface with 16-bit I/O. What happens when writing flash via STMCubeProgrammer is the first 2160 bytes of ea...
Hi,I'm working on layout routing from STM32MC257AAK(Package: VFBGA424) to LPDDR4 (32bit).I have read the "Memory layout rules" in the App-Note AN5724.For a good LPDDR4 signal timing it is usefull to do a "Line-Length-Matching" on the LPDDR4 signals, ...
Hi, As I communicated previously I am currently working on upgrading our EV charging solution from OpenSTLinux Ecosystem v4 (Linux kernel 5.15) to Ecosystem v6 (Linux kernel 6.6).The following are my targeted components abd versions to upgrade: Linux...
Hi, I have made a custom board with stm32mp135f and I have encountered some problems:1. It seems like the stm32cubemx software is not generating .dts file when generating code, and I don't know the syntax for editing the stm32mp135f-dk dts file.2. I ...
Hello everyone...I have issue after transmitting data to usb in host CDC the main function will not executes but it will executes after 20 micro Sec i don't know which is causing my main function to stop it's execution, I am using USB host fs with to...
