AM335x EVM-SK Device Tree Overlay

Steve Jacot-Guillarmod

Hello,

I'm using Yocto with [meta-ti] to create images for the Ti's AM335x EVM Starter Kit (linux-ti-staging 3.12.10)

Since last days everything went perfectly fine, but I've now some issues with the device tree.

I created a device tree overlay (dtbo file) to enable SPI0 and now I'm looking how can I load this overlay during the runtime. I saw that the beaglebone team created a capemgr system to load dtbo dynamically (based on the I2C EEPROM data of the cape). 

My question is, how can I load my overlay on my linux who didn't implement the capemgr... Is there a standard way to do that ? It should be possible I guess, but I'm not a device tree specialist.

Thank you in advance for your help !


Best regards
