Is it okay to use the following connection for eMMC memory on the STM32MP157AAB3?Also, is it possible to set the eMMC memory to boot mode with this connection?PB14:SDMMC2_D0PB15:SDMMC2_D1PB3:SDMMC2_D2PB4:SDMMC2_D3PB8:SDMMC2_D4PB9:SDMMC2_D5PC6:SDMMC2_...
In the RM0506 rev. 1 file in chapter 14 (DDRPHYC), the DDR3L pins don't match the reference schematic in the examples-of-ddr-memory-routing-on-stm32mpus.zip file.In the STM32MP21XXAN_DDR3L-[No Variations]-A01_Schematic.PDF project, the DDR_A8-DDR_A31...

Hi all,I'm trying to get a USB Gadget device working in Linux on the STM32MP257F-DK board to expose a Mass Storage device to another system. I'm trying to use CN15 for this function but I can't get the bound gadget to show up on the other side of the...
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...
