I have a STM32MP135F with a 3V3 47mF supercap on its VBAT line.Internal RTC appears to work fine with power outages up to 3 or 4 hours, whereas I hoped one day. I see in datasheet "Table 27. Current consumption in Vbat mode" that I can tweak VBAT pow...
I'm trying to perform the first boot on the STM32MP257F-EV1 following this guide: STM32MP25 Evaluation boards - Starter Package. I've connected the LCD screen to the board according to the instructions.The board is powered by USB-C on CN21, and the ...
Hi everyone,I'm a beginner when it comes to STM32 MPU, and from the very beginning I've had an issue with the HDMI output on my STM32MP257F-DK board, which I received from my university. Naturally, I wanted to start with the Starter Package to explor...
I am using a som STM32MP255 digi connectcore board (CCMP25) for an audio application. I'm using the SAI2 lines for PCM. While playback gives me some signal, capture always results in inout/output error. For my application, the som will be the pcm sla...
I making a custom ST32MP151 board with Nordic 4G, Wifi and bluettooth. I did submit a schematic and PCB review to ST via Arrow distrubitor.Only 2 sticking ponits. The DDR3 memeory connections I coppied from ST APP NOTE AN5031 page 38, ST now says th...
Hello, I was wanting to make my own camera board and I wanted to use the same camera that is on STM's Camera board MB1854 and I looked up that manufacturer part number (AS-BC538A3M6-63(1.02.A3265)) and nothing showed up, and when I looked up just AS...
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...
Hi,I am trying to understand and test secure boot on STM32MP1. I was able to compile and boot unsigned tf-a. boot failed as expected as it is not verified.generated keys.Now how to burn these below hash file? can we burn into flash and test without u...
Hi,I was wondering if ST or any ST Partners are planning to produce a System-on-Module (SoM), System-in-Package (SiP) or Single Board Computer (SBC) based on the new STM32MP257 chips?We're planning to develop using the STM32MP257F-DK evaluation board...
