Hello everyone,I have a custom board based on STM32MP157A (rev. Z) and I am trying to boot from emmc; I am able to boot sucessfully from SD card; I flashed the same image to the emmc with the ST MX Cube Programmer and, if get into u-boot from SD card...
I'd like to move from mickledore to the current ST offering on scarthgap. We are using the STM32MP157D.We require a web browser, and WebKit worked well for us on mickledore using QT5.Since QT has been spun out to a plug-in and it is unclear how well...
I would like to use MDMA on Cortex M4 to move data from DDR to SRAM in order to overcome the SRAM size limitation, especially in Ecosystem 6 secure context when a SYSRAM bank is dedicated to OPTEE.My idea is to move to DDR some data structures used b...
ST Dev team have successfully created a web browser with Qt WebEngine and deployed that into the MP257 processor.The browser has been made in kiosk mode. There is no official benchmark about that scenario.My question is how well supported is the MP25...
I am stuck trying to run STM32MP215DK M33 firmware examples on an (unmodified) ostl distribution I built.I went through the getting started tutorials no problems, now starting to experiment with customisation, but have got myself stuck. Some advice ...
Hello,I am testing a custom board based on STM32MP257FAI3 with two DDR4 MT40A512G16And STM32DDRFW-UTIL cann't pass through PHY initialization. I found that CubeMX 6.17.0 still allows DDR A19 pin mapping, despite the pin A19 isn't assignable for both ...
Hi,Can I use only M33 core as a standalone controller on stm32mp257 evaluation board without need of linux operating system and DDR
I spotted that the documentation and code examples do not match for port pin assignments for LED2 and LED 4.The user manual manual does not match the schematics:Code examples do match the schematics, so just a documentation error I think.EDIT: There...
HiI'm trying to configure a camera chip (Nextchip nvp6324) that outputs mediaformat MEDIA_BUS_FMT_UYVY8_2X8.There are examples to setup IMX335 sensor to a CSI-2 interface, but how to configure this format ? BR Raimo
Hi Team,I am working on a custom STM32MP255 board with OpenSTLinux (Yocto, kernel 6.6).I want to use USART6 only in Linux (no need in TF-A or U-Boot).Console is on USART2 (ttySTM0). USART6 is intended for RS232 communication.Device Tree Configuration...
