I'd like to connect one USB port to the RTOS, running on the Cortex-M4. According CubeMX this is not possible (no square availble to tick). Is this really not possible?According the datasheet (DS12505 Rev3, page 19, 'Block Diagram'):USBH is connected...
Hi,In order to compile c-project directly on STM32MP157C-DK2 I've installed GCC 8.2.0 on the board but cannot manage installing libc6-dev library (or any other suitable one).Could you please help me to figure out the proper way how to do?For now I'm ...
Hello,I have followed this link: https://wiki.st.com/stm32mpu/wiki/X-LINUX-AI-CV_OpenSTLinux_expansion_package and successfully flashed STM32MP157c-dk2 device with AI OpenCV image.Now, I am trying to install python package scipy on the device. But it...
Why after$ source ./layers/meta-st/scripts/envsetup.shaliases is empty? What for?
I have seen some stm32mp157 boards from third parties do have a backup 3VDC battery attached to their RTCs, so it won't lose the time when powered off. Is there any way to connect a backup battery to the RTC circuit on the stm32mp157c-dk2 board?-albe...
I need to customize the TF-A en.SOURCES-tf-a-stm32mp1-openstlinux-4.19-thud-mp1-19-10-09.tar.xzOur custom board have a different pin selection for UART4 debug as you can see below, the UART4_TX pin is not on the STM32_PINMUX('G', 11, AF6), but is on ...
On most cases the script "create_sdcard_from_flashlayout.sh" futile. Built-in card reader today is preliminary remains on notebooks. As result very often a sd-card used over a usb adapter. On a remote virtual machines always it will be used over a c...
Hi all,i want to use some hardware peripherals in OP-TEE. I got the GPIO driver (stm32_gpio in core/drivers) to work with my PTA (Pseudo Trusted Application). I now wanna use the I2C peripheral using the stm32_i2c driver.I coundn't find any example c...
We brought stm32Mp157C-DK2 board for our prototype testing. I can able to work on the A7 and M4 also ran examples. After 3 days of our work the Ethernet communication is not working. The LED's on the connector is not glowing. I check in Linux termi...
