Hello,I have a Yocto Project with st-stm32mp1 layer, using Poky distribution along with customized CubeMX machine that I created using st-stm32mp1-addons layersI need to use the spi5 module, so I activated it through CubeMX for the "A7NS" runtime con...
Hi, can someone help with ADS124S08 SPI ADC and its linux driver? I think the driver is correctly probed. I see /sys/devices/platform/soc/44004000.spi/spi_master/spi0/spi0.0/iio.device0/in_voltage0raw ...etc but it seems the device does not reply.Thi...
Hello ST Dear ST Community, I'm currently trying to migrate my solution from stm32mp1-openstlinux-5-4-dunfell-mp1-20-06-24 to stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15 Im using a ST7789V Based LCD, and its working trough /dev/fb0 and ...
Hi, I have an application where the SPI master is sending data every 2 mSecs. The STM32MP157F-DK2 SPI4 and SPI5 are in slave mode. They are receiving the data as expected but the data is skipped between each transfer on SPI4 and SPI5. The application...
Hello,I'd like to setup a DMA transfer to feed a SPI Display with 8192 bytes per DMA cycle. To offload the MP1 I want to do this with the help of the M4 coprocessor. For my tests I am using the CubeIDE and a custom board. As a basis for learning I tr...
Hello Everyone, I am working on a custom board based on STM32MP157F-DK2. Our custom board have two external ADC (AD74413R) connected to the main processor. I have changed the device tree added proper driver for the external ADC. While reading the fi...
Hi there, I have started looking into writing a test program/script to test the functionality of the one of the SPI bus interface (which in the current board called SPI6). Now when I looked into the kernel (the below is the STM kernel we are using at...
HelloI have an STM32MP135x-DK board and have built my own openstllinux image and rootfs for it as shown in this article.https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_PackageNow I'm trying to get spi5 to show up in /dev so I can use spidev t...
My device tree:spi4_pins_csa: spi4-0 { pins { pinmux = <STM32_PINMUX('E', 12, AF5)>, /* SPI4_SCK */ <STM32_PINMUX('E', 14, AF5)>; /* SPI4_MOSI */ bias-disable; drive-push-pull; slew-rate = <1>; }; pins2 { pinmux = <STM32_PI...
Hello everyone,I would like to implement a basic spi communication with an sx1276 transceiver using CM4 as master in standalone mode in order to get the chip id. The spi5 configuration has been done using stm32cubeide which is the way i did it with a...
