Hi,We're using STM32MP157FAA1 for our products. our kernel version version is 5.15 & dunfell Yocto. Our system requirement is to enable a pwm using lptimer [ PD13 ] that serves even in low power mode. below are our queries:1. As we understood it need...
Hello,i am working on STM32MP257f-EV1 board to get access for vd55g1 camera.so far i have flash the board using FLASH-stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v25.06.11.tar.gz starter package and used FlashLayout_sdcard_stm32mp257f-ev1-optee.tsv ...
Dear Sir/Madam,I hope this email finds you well.I am currently designing a custom PCB board based on the STM32MP157FAC1 microprocessor and associated STMicroelectronics components. I would like to kindly request your support in reviewing and verifyin...
Hello,with my colleagues @LOrci.1 and @Raggio we are testing a SOM based on STM32MP257F line, running OpenSTLinux 6.6. Our SOM is connected to an expansion board originally designed for MP1 SOM by ST (STM32MP157C line).For video output we use the DSI...
I am trying to probe TC358743 (HDMI to CSI ic) to STM32MP257f-dk. The ic is able to take input from the HDMI from my laptop (I is being checked as when i give an edid as input from v4l2 then the screen of my laptop gets extended).The problem is in re...
Hi,I am working on custom board with STM32MP257. I am trying to enable i2c7 but it is RIFSC blocked.When I try to change the rif configuration for i2c7 the flashing process is interrupted and I cannot download the FW.Any help would be appreciated.Tha...
So coincidental enough all the projects I have done before required a RTC /w LSE. I am now working on a project that does not need a LSE, and I am finding that TF-A keeps throwing a panic because of this. The protos we had fortunately had the circuit...
We have designed a product using the MP257, and based the board layout of the EVK and we are now taking the combined product through RED & FCC testing.Generally the board is very quiet, but we are experiencing problems with the Ethernet clocks and we...
Hello! I'm just getting started with an STM32MP257F-DK and B-CAMS-IMX module. I've followed the instructions for connecting the B-CAMS-IMX and have populated SD cards for booting with both optee and extensible layouts, but I am having an issue gett...
Hi,I am in the middle of the project development based on STM32MP257FAK CPU. Originally we were using 8Gbit Micron chip (MT53E256M32D1) which became obsolete in the middle of the development, it even seems that most of the 8Gbit Micron chips are now ...
