Recipe for gcc-arm-none-eabi-native fails. Download checksum error with kirkstone.
I am puzzled with a curious build problem:The recipe gcc-arm-none-eabi-native downloads gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 but the download finishes to early (at 100MB instead of 150MB). Therefore the checksum check fails.BUT:If I co...
The STM32MP157 is configured for ADC acquisition within the M4 core, and the ADC data is carried using the DMA method. It turns out that the sample rate and the sampled data are correct when debugging with the development board MCU start-up method Debug,
The two graphs above are the data obtained from different cores. The left side is the MCU method start, the sampling rate is 1.6M, the acquisition of 1KHz signal, the acquisition of 1600 points is correct; the right side is the EMMC from the A7 core ...
Is it possible to power the board without using the USB-C ?
On the STM32MP157-DK1 schematic there is a note to say "WARNING - do not supply 3V3,5V from Arduino shield", even though it looks as though pin 5 on CN16 is electrically connected to 5V_VIN via a 0R resistor.It's going to be very inconvenient to use ...

Resolved! ETZPC and kernel FIT image
Hi all!!Follow the wiki page, I added support to kernel FIT image in my Yocto distro for the board stm32mp157c-dk2 based on openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23.Just I added the option: MACHINE_FEATURES += "fit" and I selected BOOTSCHEME_LA...
Resolved! STM32MP157A-DK1 StLink LED is always red
Hi,When I power on my STM32MP157A-DK1 board, ST-LINK LED (LD4) is always red. On my Linux system when I connect the board through ST-LINK micro usb port (CN11), it is only detected as 'STM32 Virtual ComPort', and not detected as StLink device. And wh...
Problems with CubeMX and TIM1+DMA for PWM on STM32MP157 - DK1
I'm trying to get PWM running on an STM32MP157-DK1.When i run the example code "TIM_DMABurst" there is a PWM (had oscilloscope on Pin). Then I configured TIM1 on Channel 1 and the DMA on Stream2 with CubeMX. The generated code looks exactly the same ...
