SPI Read in uboot - SPI2
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.
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...
Resolved! Directing Printf to UART4 Linked to Onboard ST-LINK of STM32MP157C-DK2
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...
Resolved! M4 Core ITM trace
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...

Resolved! Where to find the device trees (*-a7-examples.dts or *-m4-examples.dts) ?
Hi,I'm developping an application where we want the cortex-M doing some power management (with OpenAMP) and the cortex-A taking picture and saving it on SD card.I have the STM32MP157A-EV1.I used the OpenAMP_TTY_echo_wakeup sample that I modified for ...
How configure 2 MCLK connected to I2S_CKIN
Hi!I use STM32MP151 chip. Use Linux OS. Two master clocks(MCLK) clk_x8(for 48000) and clk_x11(for 44100) connected to I2S_CKIN throw switch. GPIO select it. Can I configure SAI driver and device tree for this situation?
