I'm currently trying to boot STM32MP257 DK board.I managed to do it in the past with starter and developer package. I recently got back to it and tried to boot it again but without success.I tried to upload starter package to SD card and EMMC, both w...
HiWe have a Custom Board based from MB1272 dev kit.Our system needs to connect the RGMII to a Marvell Switch Chip where that Switch is Managed MDIO from a different MPU.As such we need our STM32MP157 MPU to run in a fixed phy mode and use the RCC to ...
I would like to add a custom resolution hdmi display (1024x600) to my STM32MP257F-DK board is it possible as the dmesg output is as follows [ 930.525408] [drm:drm_helper_probe_single_connector_modes] [CONNECTOR:32:HDMI-A-1] [ 930.590130] stm32-di...
I have tried changing the ldo7 of stpmic25A in stm32mp257f-ev1,i have a custom board using stm32mp257fai3 and stpmic25a, where im using LDO7 for ethernet which needs 1v. so i tried experimenting the voltage first in stm32mp257f-ev1 EVK board and i ap...
Hi ST,We have developed a custom board based on the STM32MP257F-DK design, with the primary difference being the use of the STM32MP255DAK3 processor in place of the STM32MP257F. All other components and configurations—such as RAM, eMMC, and SD card i...
Hello ST Community, We are developing a product based on STM32MP151 which has 2 (WKUP) GPIOs connected to wake our battery-powered product from sleep or shutdown. Can somebody please let us know how we can detect which GPIO triggered the wakeup in ...
Hi,I'm trying to understand what the viable options are.my goal is to be on more recent versions of kernel/uboot because there are features upstream that I need.my preference is to be following upstream.Current situation is that i'm using stm32s fork...
Hello everyone,I am reaching out to the community regarding an issue my team is experiencing on the STM32MP257F, specifically within a project running on the Cortex-M33 core.ContextWe are attempting to configure SPI2 to transmit data to an external D...
STM32MP151 is a PTP slave clock, and the master clock is correctly determined and configured. In the same network, multicast, E2E, and one-step configuration modes are used. Run ptp4l，Output prompt: "Received SYNC without timestamp". the actual SYNC ...
Hii, I am using STPMIC25A with STM32mp257FAK3 with DDR3L in one custom design and LPDDR4 in second custom design.I am able to change o/p of Buck 4, Buck 6 and LDO 3 as per the requirement by changing the voltage for the same in the device tree, under...
