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...
HelloWe are currently attempting to boot both Cortex-A35 cores of the STM32MP257 processor using an SD card. While we have successfully verified that both cores function independently under bare-metal conditions, we are facing challenges in waking bo...
I applied real-time patches to the Linux kernel, but when I measured the RT performance using rt-tests, I found that these two services were affecting it: "stm32mp-calibration.service" "stm32mp-calibration.timer." What is the reason for this?Is it ap...
Hello everyone,I'm working on porting the PCMD3140IRTER codec to the Kirkstone BSP on an STM32MP13 platform. At the moment, I have connected only two microphones (presumably the left and right ones) to the PDMDIN1_GPI1 line.The microphones are Adafr...
Hi,I am trying to test STM32MP257 hash hardware accelerator according to the following article: https://wiki.st.com/stm32mpu/wiki/Crypto_API_overview.I was able to utilize the crypto accelerator using openssl (as described in the article), but once I...
