hi, i’m unable to view spidev in /dev directory. i’m using linux lxde image from toradex. After a bit of googling

according to this link SPI Linux Toradex

By default our BSP uses the MCP2515 SPI CAN controller as available on our Colibri Evaluation board V3.x. In order to use spidev instead one needs to disable (e.g. status = “disabled”) the mcp2515 device tree node and enable (e.g. status = “okay”) the spidev one and re-generate and deploy the device tree to the target.

I’m using IRIS board. Can someone help me on how to enable SPI once i boot to linux.

Hi, there is no prebuilt image with spi enabled for Colibri iMX6s. The Steps to build kernel with SPI enabled were already provided above.

You will need to change the device tree, compile it and flash it to the module. There is no possibility to activate Spi, if the module is already booted to Linux.
