Migrating from STM32MPU DK board to custom hardware
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...
Resolved! st32mp257f: scarthgap gpu etnaviv optee clk_stm32_pll_init
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...
Is there any documentation about the different OpenSt-Linux FlashLayouts?
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,...
Issues: Accelerating Whisper-Tiny Model on STM32MP257-EV1 NPU Using ST Edge AI Tool
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...
Resolved! How to port Raspberry Pi's 7-inch touchscreen with Stm32mp157c-dk2?
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...
Resolved! STM32N6 vs STM32MP257 - Which one have the best AI?
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...
Resolved! Error Writing SLC NAND Flash - second half of each page contains repeated byte
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...
Resolved! STM32MP257 LPDDR4 routing: Line length from die to ball for STM32MP257 (VFBGA424 package)
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, ...
Resolved! OPTEE 4.0.0-stm32mp-r1 compilation and and CFG_DRAM_SIZE issue
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...
