I entered the lengths of the DDR traces from the ST official evaluation board into Excel, and the maximum length deviation is 3 mm. Is the trace routing on the evaluation board reasonable, and can I reuse it directly on my own board?
Hi,We use the USB OTG controller in host mode with its internal FS PHY.Our DT node is the following:&i2c4 { ... pmic: stpmic@33 { compatible = "st,stpmic1"; ... regulators { compatible = "st,stpmic1-regulators"; ...
Following the guide for the Developer Package, it describes creating a helper script for your custom board. Thhat works great and helps get you going. So, I generated a STM32CubeMX project and built it. Device Tree files are generated accordingly. ...
Following the tutorial here, when I get to the step "To generate binary to flashing via Cortex-A", the helper script fails to build when given the 'programmer' argument. The problem appears to be incorrect configuration of the path to a device tree ...
Platform:SoC: STM32MP257Sensor: GC05A2 (5MP)Interface: CSI-2 Issue:I'm working on camera integration with GC05A2 on STM32MP257. The raw image quality is acceptable, but after enabling AWB and CCM in the ISP pipeline, the output image shows severe noi...
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 ...
