The functionality of the spi-imx driver working fine When referring to a GPIO in a device tree node, you use the bit/bank mapping scheme. This document mainly introduces several important device tree files in iMX6 development board (iMX6Q, iMX6D, iMX6PLUS). Most modules offer additional (non-standard) SPI interfaces, to enable these device trees or board files aka platform data customization linux-device-driver spi device-tree edited Dec 5, 2018 at 14:57 asked Dec 5, 2018 at 14:48 ddbug Hi, We are trying to configure the SPI device on the Apalis imx8. These files are often used in subsequent device driver analysis. The configuration is performed using the device tree This hardware description is a combination of the STM32 microprocessor device tree files (. dtb file which I’m modifying the . 0A with When i debuggging the code spi->chip_select is configured, but doesnot reading the correct data ( like REV ID) from the slave device. This article explains how to configure the SPI internal peripheral [1] when the peripheral is assigned to Linux®OS, and in particular: how to configure the STM32 external SPI devices present either on the board or on a hardware extension. It's confusing as to what the correct way to define an LCD in the device tree for Linux. Let’s go through some steps to help resolve this issue: Device Tree Configuration: We've created three new device trees that re-purposes the parallel LCD port (J15) on our Nitrogen6x, BD-SL-i. dts extension). MX6Q pad name). MX6 and Nitrogen6_Max boards. How shall I do it? Which device tree should I modify? Kindly share the steps. This file can then be maintained and Hi, I’m the Toradex AI Assistant. MX6 SPI interface device tree binding is documented at Documentation/devicetree/bindings/spi/fsl-imx-cspi. In this blog post, I'll walk you through the process of using SPI on the Imx6 This page provides a detailed explanation of device trees within the meta-imx BSP, how they are structured, and how they describe machine-specific hardware for i. 11. I've read the binding Technical Support wifi, spi, colibri, imx6ull, device-tree, yocto, imx6 BlackCableSociety January 22, 2025, 11:55am 1 Hello, Until now I used some Colibri iMX6ULL 512MB WB IT V1. Our setup consist of a (Custom) Apalis board we call “Core” and one of more Slave device’s we call “Hubs”. See the Device tree for an explanation of the Boundary Devices Kernel tree for i. We connect the If the spidev device still does not appear, double-check the device tree changes and ensure they are correctly applied. This selection can be made by either fusing the SoM or adjusting the boot select jumpers if populated. txt. So I'm lazy, or I'm hoping to benefit from kernel changes and maintenance. Review the kernel configuration to ensure CONFIG_SPI_SPIDEV Ezurio turns design possibility into reality with a comprehensive range of RF modules, system-on-modules, single board computers, internal antennas, IoT devices, and custom solutions. The code below is in the imx6dl-colibri-eval-v3. We did customise the device tree for our board in particular to ad an Intel i210 PCIe Ethernet adapter and to enable access to the 5 SPIs for Linux - Embedded & Single-board computer This forum is for the discussion of Linux on both embedded devices and single-board computers (such as the Raspberry Pi, BeagleBoard and I’m getting the errors shown in the photo of the boot log. Device tree bindings and customization The i. 2 How to build and load Kernel in Yocto Project. MX6 It looks like you’re having trouble detecting SPI devices on your Colibri iMX6 custom carrier board. When it comes to SPI I do not see any SPI commands and I believe I need to setup a custom device tree. dts version of it and then re-compiling and overriding It seems the bitbake process adds CAN and I2C to the device tree. We've created a break-out board to make it easier to As a supplier of the Imx6 Solo, I'm often asked about how to use the Serial Peripheral Interface (SPI) on this powerful processor. The Imx6 Solo has multiple SPI interfaces, and you need to connect the SCLK, MOSI, MISO, and SS pins of the 2. MX processors. 1. Pin Assignment: Refer to the Imx6 Solo datasheet to find the appropriate pins for SPI. The Toradex Support team will follow up with you shortly! Did you like my answer? 👍 👎 Hello, It looks like you’re having trouble detecting SPI devices on Topics tagged spinext page →Topics tagged spi Check for Conflicts: If your board setup includes an MCP2515 SPI CAN controller, it might be enabled by default, which can interfere with SPI device detection. MX6. dtsi extension) and board device tree files (. The SPI interfaces are defined in the i. Make sure to disable the Our devices can load it from either microSD, eMMC, SATA or SPI. Hi, I am new to yocto and I want to operate the SPI peripheral on iMX6 board. For example, AUD_PWRON (schematic net name) maps to DISP0_DAT23 (i. Contribute to cboyd33/linux-imx6 development by creating an account on GitHub. With The device-tree compiler and the U-Boot bootloader support the concept of applying changes to a base device-tree to make it easy to implement add-on boards such as a touchscreen The device tree solves these problems by moving board / device specific code out of the kernel and into the device tree file. The standard SPI interfaces are enabled by default.
