Hello,I'm trying to embed an app in the st-linux distribution. I mean that the goal is to have it compiled with bitbake and integrated in a custom st-image-weston.I tried to use the gtk hello world example of Developper section (that run without prob...
HelloI switched to the Distribution package to have access to the layers provided by ST.After I use command repo sync I, a file named layer is created.When I:DISTRO=openstlinux-weston MACHINE=stm32mp1-disco source layers/meta-st/scripts/envsetup.sh I...
Hi, I did some power measurements with a Joulescope which measures the full power given to the card (no distinction between VDD, VDDCORE, etc.) - we chose this way for first measurements without card's resistors modification.I mostly followed the sam...
Hi ,Actally i want to read a PISO shifht register as spi slave.Device Tree: spi2_pins_a: spi2-0 { pins1 { pinmux = <STM32_PINMUX('A', 9, GPIO)>, /* uart8_tx */ <STM32_PINMUX('I', 2, GPIO)>, /* uart8_tx */ <STM32_PINMUX(...
Good afternoon, Olivier. Thanks for the help. But I saw a problem with MPU Serial (COM3). I ran ipconfig in Linux and found the real address of usb0 192.168.7.2 after that, the console worked.But the board does not allow debugging. I must have done s...
Hi, I am developing firmware on the STM32MP157C-DK2 in engineering mode and using STM32Cube_FW_MP1_V1.4.0 and STM32CubeIDE. I must say this is my first project with a STM device and the tools. I am unable to direct printf to the UART4 linked to the o...
