Hello,I am trying to use the DDR test suite from Cube IDE with a custom board based on the STM32MP257FAI3 with 32Gb of LPDDR4 (MT53E1G32D2FW-046 WT:B). The board doesn't have engineering boot available, but it does have USB/UART boot, so I have been ...
Moved to the MPUs section - STM32MP25 is an MPU, not an MCU.HI, I AM NEW TO THIS COMMUNITY, I NEED TO KNOW ABOUT THE WORKING AND HOW TO USE THIS, I HAD FEW QUERIES ABOUT THE OPENS...
I am using the STM32MP257F-DK with a WiFi-BT module. WiFi is connected via SDIO pins and Bluetooth is connected using UART6 pins through the 40-pin header.I am testing the HFP profile on the BT module. When I run the dial-number script from the ofono...
Hello,I notice that on stm32mp257f-ev1 board the USB_DRD port (CN15) is active only if USBPD_DRPSI_CM33_NonSecure_stripped.elf firmware is running. I need to run a different firmware on M33 while using the USB_DRD port. Searching in board's DT I fou...
I am trying to measure voltages using the STM32MP157C's built-in ADC on channel 18 in differential mode, but keep getting wrong values. Linux kernel is 6.1.28.Here are the relevant bits from the Linux device tree:&pinctrl { adc_pins_mx: adc_mx-0 {...
Hello,we have an issue with a STM32MP1 and EMMC. The only boot source is SDMMC2 from eMMC-Flash.So far it works fine, but when we try to initiate a "reboot" in linux the system hangs and won't start again. If we do a reset in u-boot, there is no prob...
Working with STM32MP257F-DK + IMX335 camera + Quectel EG916Q-GL modem. Successfully recording to eMMC but facing image quality issues:Yellowish tint, Overexposure, White lines in recorded videoVideobalance settings (brightness=0.2, contrast=1.2, satu...
Hello, I would like to ask a question about the U-Boot USB enumeration of STM32MP157:Using a custom board with the STM32MP157 (FUSB302MPX), openSTlinux6.6,:Problem description:Through "STM32_Programmer_CLI -c port=usb1 -d ../../FIP_artifacts/arm-trus...
Hello,I have tried following the https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_OTP_management to achieve this.I have tried configuring CFG_BSEC_PTA=y CFG_STM32_BSEC_WRITE=y CFG_WITH_USER_TA=yinto the meta-st-stm32mp bsp and verified that it w...
HelloI'm considering the requirements and learning process for designing a board with the STM32MP2.I've never done DDR4 routing before—what's the best starting point?Also, is it feasible to design such a board using a tool like KiCad, or is a tool li...
