Hello,We had to switch out an SD card for eMMC and we kept with SDMMC1. I am aware of having to burn the fuses to get eMMC to default to SDMMC1 which I did. I was able to get it to flash successfully, and now when you switch it to 010 it will boot fr...
Hello,I am running a Linux image based on meta-st-stm32mp (hardknott branch).I currently have the following in my host device tree:reserved-memory { #address-cells = <1>; #size-cells = <1>; ranges; ...
I need to migrate my project from STM32MP135F-DK board to custom hardware (SoM based on STM23MP135DAF7). To build images I use Yocto Project (Scarthgap) with meta-st-stm32 layer.As a begginer in device trees and BSPs world, I would like to get some r...
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...
Hello, I have STM32MP135F-DK board and raspberry pi camera module v2.1 but board does not see cameraI guess I have to modify stm32mp135f-dk.dtb file. But how should I write settings like OV5640 or GC2145 in dtb filelike that gc2145: gc2145@3c { co...
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...
