Ask questions and find answers on STM32 microprocessors and dedicated embedded software solutions, such as Yocto SDK, Qt, and OP-TEE.
Hello, I have two questions : (1) Is I2C5 the one on which the peripheral can be connected on the I2C lines on the Arduino connector with the cortex M4? I checked this and it is I2C5.PLease correct me? (2) I was trying to search/look the BSP methods ...
Hello, There may be another variant of this question available but I am reposting it as I couldn't get any success so far redirecting prinf messages to uart4 and viewing them on serial terminal utility.below are the snapshots which shows I have mappe...
Hi,I am working on a functionFS usb gadget based on gmidi. Following the gadget_configfs.rst and using stm32_usbotg_eth_config.sh as starting point was straight forward. After writing the shell script and modifying my device tree configuration to sup...
This is how I would like to use rs485:&usart3{ pinctrl-names = "default", "sleep"; pinctrl-0 = <&usart3_pins_mx>; pinctrl-1 = <&usart3_sleep_pins_mx>; status = "okay"; uart-has-rtscts; linux,rs485-enabled-at-boot-time; rs485-rts-delay-ns = <80...
Hi,Out kit use the chip stm32mp157C.The schematic show the PHY configuration.dts_file_relate2eth.txt: my device tree code related to the ethernet.loginfo.txt: show error information.Please advise how to solve it.Thanks,QiZhang
We are using OpenSTLinux as base distro for configuring and developing product on a custom STM32MP1 based embedded board. We plan to develop some testing and validation plans for the same. Just wanted to understand what sort of testing is carried out...
I have a design based on the STM32MP157C (technically the Octavo SiP) which simulatenously uses PA0, PA1, ANA0, and ANA1. While measuring analog signals on the device, I'm noticing that the CPU is biasing the ANA0 and ANA1 signals -- based on a measu...
Hi everybody,I would like to simulate a USB scanner device using libcomposite, so I modified the USB FIFO sizes in the DTS as follows:usbotg_hs{ u-boot,dm-pre-reloc; pinctrl-names = "default", "sleep"; pinctrl-0 = <&usb_otg_hs_pins_mx>; ...

Hi,I'm trying to bring up a custom board based on STM32MP151C MPU. The design is widely taken from the devkit.I'm booting from SDCARD and bootpins are set accordingly (b101).One thing that is changing is the I2C4 pins for PMIC interface (still on I2C...
