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...
Hello,I am working on a custom board derived from the STM32MP157F-DK2 reference design and currently validating the basic bring-up.I have a few questions specifically related to the Cortex-M4 (MCU) core on STM32MP157F:Checking MCU execution via JTAG/...
Hi,I am trying to work with the USART6 which is connected to is connected to PF13 (TX) and PF14 (RX) on the extended GPIO.It looks like the SCRIF does not allow access to this USART, wven though the OPTEE configuration seems to enable it:from optee/....
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...
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...
How may I use STM32MP257F-EV1 PCIe in *Endpoint Mode*? I am looking to connect two STM32MP257F-EV1 devices together via PCIe; one device in PCIe host mode, and the other in PCIe endpoint mode.1) Physical connectionAccording to the boards user manual...

Hi Team,Does STM32MP257F-DK supports OpenSTDroidIf supports where can i find the starter package for this Discovery board.
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...
