Hi,My name is Siyabonga.I am working with the STM32MP257F-EV1 board and have downloaded the STM32MPU-Ecosystem v6.1.0. I am trying to generate a pulse-per-second (1PPS) signal using the Ethernet module.I followed the guide titled "How to configure PT...
Summary:HDMI output on STM32MP257F-DK board does not function with 800x480 HDMI display. The ADV7535 DSI-to-HDMI bridge driver loads and binds successfully, but the probe() function never executes, leaving the bridge in powered-down state. Display sh...
Hi,we use the STM32MP157C with almost the same RAM layout as the STM32MP157F-EV1, except that the SDRAM chips are from Micron (MT41K256M16). The PMIC is also the same as the one on the evaluation board, and the settings therefore are identical. TF-A,...
Hi AllI have a question about the debugging the M4 when we are using OpenAMP Lets say we have a simple example from the docs , and i am creating debug config and i am expecting the code to be flashed and the communication to work (while debugging) bu...
Hello,Im having an issue with flashing of OpenSTLinux on STM32MP157F-DK2 ------------------------------------------------------------------- STM32CubeProgrammer v2.21.0 ----------------------------...
Hello!I am in the progress of setting up a Yocto based build for a custom board based on a STM32MP157C. I am using "vanilla" Yocto scarthgap with the respective ST meta layer: https://github.com/STMicroelectronics/meta-st-stm32mp meaning I created a ...
I've inherited a board that is based on an STM32MP135AAE3 and has an external DDR (W63AH6NBVABI, a DRAM 1Gb LPDDR3 from Winbond). It appears I need to create a DDR.h file similar to the stm32mp13xx-ddr3-4Gb.h or stm32mp13xx-ddr3-8Gb.h files that STM...
The project requirement is to use optical ethernet with STM32MP257F. I want to try this interfacing first at STM32MP257F EV1 with some copper to optical Ethernet converter module, but in STM32MP257F EV1, Ethernet pins are not available for interfacin...
Hello Everyonelinux kernel version: 6.6.78After configuring the device tree, I can see the SPI device /dev/spidev6.0 on the STM32MP257F-DK board. However, when I run spidev_test[1], it returns the error message "Invalid argument."I tried using an osc...
Hello, I am using a STM32MP135F on a custom board which is working well using SD Card (sdmmc1).The SDCard is partitioned as: 1) fsbl12) fsbl23) fip4) bootfs5) rootfsFrom the SDcard system, I try to prepare the eMMC (4GB, sdmmc2).I tried different con...
