I just need to confirm something. I read in the RM Document that STM32MP157 does not support ODT for LPDDR3 SDRAM but it does have a DDR Controller and PHY which supports LPDDR3. I just wanted to know if I can freeze LPDDR3 for my case? I suppose not...
Dear all:I am currently using the distribution version:V5、rt 6.1.82-rt patch、stm32mp257Prompt in Wiki，need disable CONFIG_CPU_IDLE，But in reality, it cannot be closed.Why am I paying attention here? Because I encountered an Oops exception during runn...
I am trying to probe TC358743 (HDMI to CSI ic) to STM32MP257f-dk. The ic is able to take input from the HDMI from my laptop (I is being checked as when i give an edid as input from v4l2 then the screen of my laptop gets extended).The problem is in re...
I've got a custom board built around an STM32MP135AAE3. It's designed to have an eMMC instead of an SD card, the problem is that the board was not laid out correctly and the JTAG isn't connected.I'm having trouble writing to the eMMC (that's another...
Hi!I'm looking for an appropriate DRAM for the MP257.I know there is a table about validated DRAM for MPUs.https://wiki.st.com/stm32mpu/wiki/Validated_DRAM_on_STM32_MPU_portfolioMy question is if there is a DRAM standard i csn follow if I want to try...
Hello ST Community,Custom STM32MP2 board with STM32MP257FAK fails rootfs mounting from eMMC in HS200 (CRC errors), works at 52MHz DDR.In the device tree side only difference is removing HS200 property and added Max frequency to 52Mhz.&sdmmc2 { pinct...
Hi Team,Does STM32MP257F-DK supports OpenSTDroidIf supports where can i find the starter package for this Discovery board.
Hi everyone,we applied the ST FWU reference solution on our own platform based on the STM32MP157F.The solution was taken and adapted from the ST Yocto layer meta-st-ota (https://github.com/PRG-MPU-CUST/meta-st-ota).We have a few questions to clarify ...
I have CubeMX 2.0.0 and I notice that if I want to enable DSIHOST, I need to first enable HSE.But the clock configuration of the DSI does not require HSE. It seems that the clock configuration of DSI seems to work with HSI in CubeMX 2.0.0.So, the que...
I have an STM32mp135f-dk board that I have been using openstlinux-6.1 to develop images on.For my board, I made a custom device tree "iris.dtb" which I intend to use instead of the default "stm32mp135f-dk.dtb".I ran into an interesting issue where u-...
