Hi all,i'm developing firmware for STM32MP135F-DK board to communicate with some external chips in I2C1.No problems if I communicate with other I2C chips (clockgen, eeprom, io expander).Communicating with the RTC PCF85063 chip happens that no problem...
Dear ST Team,I am currently working with the STM32MP257x-EV1 evaluation board to validate the BSP, following the official setup procedure provided on your Wiki.At this stage, I am verifying OpenAMP communication between the Cortex-A35 and Cortex-M33 ...
I am working on a STM32MP157D-DK1 board, and I am trying to follow the guide from the wiki to start the coprocessor from u-boot:https://wiki.st.com/stm32mpu/wiki/How_to_start_the_coprocessor_from_the_bootloader#Start_from_the_bootcmd I have pulled th...
Hi,I have STM32MP257F-DK and Yocto linux installed to it.I have tried to get spidev working on SPI6, but no luck so far./dev/spidev6.0 won't appear to filesystem.Has anyone tried this combo and got it working?Any working SPI configuration would be hi...
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 {...
