Hello,I am running on a stm32mp255dak processor with Linux running on the A35 core and FreeRTOS on the M33 core. I am running the M33 core code out of DDR.I am seeing an issue where the M33 core performance takes a hit and missed deadlines when the A...
my code only made changes the io, no rtos, no interrupt, but it cost over 1 us. the picture is that io sta. and clock
I'm investigating 2.5Gb Ethernet PHYs for our STM32MP257D board. Most, if not all, require SGMII which is not explicitly supported in the ST MPU documentation.Anyone been down this road?Anyone know of a compatible 2.5Gb PHY that can use the STM32MP2...
Hi,I’m having an issue with flashing OpenSTLinux Android (OpenST-Droid) on the STM32MP257F-EV1 board.I followed the instructions in the following document:STM32MPU Distribution Package for Android - stm32mpuHow to build OpenSTDroid distribution - stm...

Hi Everyone,I'm trying to understand the NOR Flash boot sequence of stm32mp257f-ev1. Im using generated FlashLayout_nor-sdcard_stm32mp257f-ev1-optee.tsv to flash the st-image-weston image.I want to understand how exactly the boot sequence is started ...
I'm working with the STM32MP257F-DK board and using the NXP IW612 wireless module, which is connected through the Murata uSD-M.2 adapter via the board's microSD card slot.When I connect the adapter, the mmc interface detects it in high-speed mode, wi...
Hello,My aim is to install OpenCV and use it's functionalities on STM32MP1 board. But I coulnd't find a proper documentation about it. Could you help me with this?Thanks.
I generated the M33 code using CubeIDE by following the lab manual.During the driver initializations:MX_ADC1_Init();MX_I2C1_Init();MX_ICACHE_Init();MX_RTC_Init();The A35 halts CPU1 and resets after sometime.E/TC:0 stm32_iac_itr:192 IAC exceptions [15...
