What could be causing the SPI bus Linux Driver, not to function on iMX6Q.

[michaelbrainerd]

I am writing an application to Stream video over SPI from a Veriscite DART SOM, to a ARM Cortex-M3.

The Linux image is Yocto Krogoth:

• git clone https://github.com/varigit/linux-2.6-imx.git

this is the kernel error message:

• spi_master spi0: cannot find modalias for /soc/aips-bus@02000000/spba-bus@02000000/ecspi@02008000/ecspi1grp
• spi_master spi0: Failed to create SPI device for /soc/aips-bus@02000000/spba-bus@02000000/ecspi@02008000/ecspi1grp
• spi_imx 2008000.ecspi: probed

Hi Michael

some boards may have pin conflicts ecspi1 with other modules, like imx6qdl-sabreauto.dtsi :

linux-2.6-imx.git - Freescale i.MX Linux Tree 

so one carefully check ecspi1 muxing options

Best regards
igor
