Hi, I'm doing a custom hardware design. I'd like to use LPDDR4 but only at 16bits of data width.Is there a list of LPDDR4 parts from Micron, ISSI, or others that are known to work with the STM32MP257?Are any parts that claim LPDDR4 ok?Thanks,John
Hello, st:The board I have on my hand is stm32mp257f-ev1.Now I have a problem. The gstreamer cannot work properly when playing mp4 format video.Does the h264 decoder need to be activated or enabled?I run this commandgst-launch-1.0 playbin3 uri="file:...
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...
Hello ST Community,I'm trying to enable SPI4 on my STM32MP157F-DK2 board to use it for a SPI-based SD card interface.In my custom device tree overlay, I’ve defined the SPI4 node like this:&spi4 { pinctrl-names = "default", "sleep"; pinctrl-0 ...
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
Hi. I am trying to connect iPhone 14 (lightning port) to OTG (CN15) on STM32MP257F-DK, but there is no connection.iPhone 14 is not charged. No USB connection is shown on iPhone.On the board:`lsusb` does not show any new connection.`dmesg` does not sh...
I created an STM project of the STM32MP157f-dk2 in eclipse.I've tried to build the entire A7 core linux code. How do I replace what's on the dk2 now? The dk2 just has the starter package on it.
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...
I am using the STM32MP157F-DK board and attempting to connect an NXP Wi-Fi + Bluetooth module via SDIO through the 40-pin expansion header. For this, I designed a custom PCB with an SD card holder and connected the SDIO lines from the expansion heade...
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...
