Hi!During loading flash_layout image to custom STM32MP1 I've got following error after staring u-boot and truing to load information to partition 0x04 fsbl1:U-Boot 2020.01-stm32mp-r1 (Jan 06 2020 - 20:56:31 +0000)CPU: STM32MP157DAB Rev.ZModel: STMicr...
Hi!Could you please give me exact details of following eth PHY error:[ 95.822137] stm32-dwmac 5800a000.ethernet eth0: no phy at addr -1[ 95.826911] stm32-dwmac 5800a000.ethernet eth0: stmmac_open: Cannot attach to PHY (error: -19)Why it searches ad...
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...
Hi,Looking at the reference manual, en.DM00327659.pdf, page 3929 it seems the simple way of debugging previous M4 processors using printf() redirect to the ITM and then using the SWO pin/STLINK interface could be used on the MP1 M4 core as well.But t...
