Hi! I am using an STM32MP153 and am working on implementing the STOP mode functionality for my application. The MCU shall wake up on a falling edge on pin PI8. The pin PG15 has an interrupt attached to it for another functionality. Before going into ...
Hi,I use in my project STM32MP153, which is a model without a GPU. My application also doesn't need any graphical representation like Wayland, X11, etc. How can I update st-image-weston.bbappend to remove these unnecessary elements?ThanksMW
Hi All, I'm trying to boot a custom board using the Starter Package through the STM32CubeProgrammer. I'am flashing the SD Card on the board through the UART interface as USB interface(CN7/USB_OTG) is not provided for the board. During this process I'...
Hello all,I'm working on a custom board based on a stm32mp157c & stpmic1 (connected on I2C4). We are using secure boot and have configured the I2C4 to work in secured mode. To control the stpmic1 from the unsecure / normal world, we use the scmi-reg...
Hi, We would like to drive pin PWR_ON to low for low power mode.First, on MCU, we use HAL library: HAL_PWR_EnterSTANDBYMode(), load to M4 and run it first, so M4 now enter standby mode.Second, on MPU, we set TZEN=0 so non-secure, allow us to modify P...
I am working on a system designed on stm32mp157c mpu. I am trying to setup a remote debugging setup wherein I am running an openocd debugger script on this stm32mp1 mpu. The target I am debugging is an stm32f405 discovery board, which is connected to...
I am working with an STM32MP157d-dk1 board, but am trying to make my own MVP board running yocto on the STM32MP157 chip and have questions concerning the use of the debug console.I believe the debugging console for the dev board runs via uart4, and i...
Hi,I want to configure the LED7 of stm32mp157f-dk2, in arc/arm/boot/dts folder there are stm32mp157f-dk2.dts and stm32mp157f-dk2.dtb file, I cannot edit .dts file since it appears as an audio file and not the text file.so I edited the stm32mp15xx-dxx...
Hi!I am using the stm32mp157C-DK2 board to communicate via FDCAN and my idea is to use it as normal mode to send and receive CAN messages. For this I have created a program in stm32cubeide and I enable FDCAN1 with the following parameters (125Kb/s): ...
Hi,First of all, I am sure I am completely overlooking something, but I can´t seem to figure this out:In CubeIDE I added the FDCAN1 peripheral for my STM32MP157D-DK1 board. I then added the device tree to the build. However, when the board has booted...
