Hi, I have a custom board based on STM32MP257FAK3, based on STM32MP257EV1 evaluation board. My board has a rtl8367s ethernet switch connected on eth2 port though rgmii. I can communicate though mdio to the rtl8367s and configure it. We are using Open...
HI ST Community,I need to compare the DDR4 configuration data before and after DDR training. could you please guide me on how to retrieve the DDR configuration data after a successful boot of the STM32MP257F-EV1 Board.Thank you.
Hello,I have developed a custom board using the STM32MP157DAC1. The pin layout is nearly identical to the STM32MP157-DK2 for all pins with the same name.I am trying to flash an SD card image using STM32CubeProgrammer, but I'm facing two critical issu...
Hello,I am working on evaluation board in that boot logs I am gettingNOTICE: Model: STMicroelectronics STM32MP257F-ev1 Evaluation BoardNOTICE: Board : MB1936 Var1.0 Rev.D-01What should I do to remove this "NOTICE: Board : MB1936 Var1.0 Rev.D-01" lin...
Hi ST Community,I’m using the STM32MP257F-DK board and successfully followed this guide: Modify, rebuild and reload the firmware Everything worked fine during the initial setup and firmware modification. Now I’m trying to flash a new image to the SD ...
I'm running a build with meta-webkit on the scarthgap branch for the STM32MP257-EV1. I'm trying to get a web browser working for a custom web page and the performance is pretty poor and I'm not quite sure why. It seems like there's a lot of people do...
Hello,we have product based on a STM32MP157 running Linux. The distribution is based on Yocto kirkstone and we are using a 6.1.82 Kernel. For the MP1s' GPU we use the open source entaviv driver that ships with this kernel. The device has a graphical ...
Hi, I'm pretty new to embedded development. I'm trying to set up a really basic 'Hello world' image for my M33 core on STM32MP257F-DK. My Linux A image has remoteproc set up, and rpmesgDmesg on linux host: [43834.220252] remoteproc remoteproc1: power...
STM32MP151 VDDCORE voltage if device above 600Mhz (800Mhz)1 VDDCORE voltage if device above 600Mhz (800Mhz). Custom Boardsee attachedThe data sheet states 2 VDDCORE voltages depending on the clock speed of part and i think yoiu can also set the clock...
Hi,we are developing a custom board based on the STM32MP157C. We would want to use several GPIOs for buttons. We have most of them working, but a couple GPIO pins do not yield input events to the Linux kernel.The problematic pins are PC1, PC2, and PH...
