Hi everyone, Hi everyone,I’m currently designing a custom board based on the STM32MP157FAC1 evaluation board, and as part of the process, I’m working to estimate the power budget for the design.However, I’m finding it difficult to locate clear inform...
Hello~ I am using the Mickledore version of Yocto. I want to directly apply the following:meta-st-x-linux-rt-openstlinux-6.1-yocto-mickledore-mpu-v24.06.26 to DISTRO = openstlinux-weston. DISTRO=openstlinux-weston MACHINE=mymachine source layers/met...
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 ...
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...
