Hi there, I'm building an ST-Linux distribution with Yocto (ST Distribution package) on a custom board (based on STM32MP153), and, now that I've tested it, I need to optimize the final image.My distribution should be completely headless (so no HMI an...
Hi,The MP157F-DK2 comes with an SD card attached. Weston (ver 5.0.0) with DRM works well.But if I want to run Weston(ver 10.0.1) on Buildroot, it will fail.Do I need to build more packages for Weston?I am using the version of Buildroot.a. buildroot:...
Hi!Are there any RMGII routing guidelines for the STM32MP151XXX series that are available for use?I have a Realtek RTL8211F-CG Ethernet PHY and I don't know how long the RX and TX lines should be.
*I've imported successfully of STM32mp157 dk-1 board 's schematics in altium designer and I don't know whether this processor is over advanced for application or it is must need to use for our product. even though I'm newbie with lesser yr of exp ,...
Hi, during Embedded World I got MP135F devkit. I'm not into Yocto, but guy from ST told me, that MP1 can be used with RTOS but with halved max frequency. I have experiance with ThreadX on H735.Can you hint me how to start? Are there any tutorials? I ...
I am adding the STPMIC1 on our custom board.While configuring device tree, when we are using scmi, how should device tree configuration look like? Should we still need to add i2c4 node? Or just adding scmi_regu entry will be enough?Regards,S
I am attempting to implement a second ethernet interface on STM32MP157F-DK2 by using the Arduino Ethernet Shield, which is based on the Wiznet W5500 chip. The implementation aims to use SPI assigned to A7 core to communicate with the shield, which wi...
Hello,We are currently working with the STM32MP157F-DK2 board and the on-board SDRAM (DDR3L). The memory map says that region (0xC000000-0xDFFFFFFF) is for the DDR system, however when we try to write to some of the memory locations inside this range...
Hi, on SPI, does anyone know why every 8 bytes then it has a big gap?We tried:1MH, no gap,2MH, gap occurs,4MHz gap bigger,8MH gap bigger than 4MHzSeem higher frequency, bigger gap We don't use DMA
