Learning Path suggestion
Hello everyone, I'm currently exploring the STM32MP257F-DK. As recommended in the "MOOC - STM32MP2 demo workshop", I'm diving deep into the wiki. I have also watched the "MOOC - STM32MP1 workshop". Of course, I have reviewed the getting started guide...
forced_mode of boot_ctx is always set to 3
Hello ST team,I came across issue here.The force_mode of boot_ctx is always set to 3, which force the MPU to boot over USB, rather than MMC. I tried to set TAMP_BKP20R(BOOT MODE) to 0, but the behavior is the same after reset.Aslo, I have another boa...
Hyperlynx DDR4 Simulation for STM32MP251
Hi! I am simulating the DDR4 memory interface with the STM32MP251. Same stack-up as the reference design. Only one memory connected (point to point).I have used a Micron model for the memory but I think all the memory models are similar.I am using 53...
STM32MP157DAC EVB: DDR3L Length Matching
Hi,I am referring to the STM32MP157D-DK1 EVB (STM32MP157DAC1), specifically the "mb1272-bdp" design file, and would like to clarify the correct method for measuring DDR3L to Microprocessor (MP) trace lengths on the PCB.My question is regarding the Cl...
Training a Face Detection Model on WIDER FACE Dataset
I would like to train a face detection model using the WIDER FACE dataset.I have already created the environment with Conda, and the training process ran normally. The training results are as follows:Using object_detection/stm32ai_main.py:python /h...
STM32MP257F-DK board - No USB DFU mode, Failed to connect STLINK (EMMC2 boots u-boot)
Found the cause and solved. what happened was:1. Plugged the host PC only into the STLINK USB-C. with SW1 set to 1, the device booted from EMMC and debug data was shown on USB UART. Assumed based on the MPU running, it would be enough power for the D...
STM32MP1 CM4 SRAM cleared after WWDG reset
Hi,i want to store some flags, bytes, at the end of my SRAM. This RAM section should preserve the information in case of a Reset e.g. WWDG1 Reset.Before WWDG1 Reset is executed some program states should be stored in RAM and after Reset could be read...
