Follow steps 1 -> 3:

https://github.com/beagleboard/bb.org-overlays/blob/master/readme.md

Then either:

sudo sh -c "echo 'BB-UART1' > /sys/devices/platform/bone_capemgr/slots"

or:

/boot/uEnv.txt

cape_enable=bone_capemgr.enable_partno=BB-UART1

Re: [beagleboard] Re: How to enable UART1 using dtb-rebuilder?

2015-11-10 Thread Davide Picchi 
Thank both of you.

Your explanations did work very well and I can load capes without a problem.

The only problem is that no capes are loaded at boot startup process. So I 
need to load the cape everytime.
The following answer 

 
didn't help further. I have that flag as default in my beagle.

The only working way seems to be:

/boot/uEnv.txt  // open that file and write the following:
 
cape_enable=bone_capemgr.enable_partno=BB-UART1

But I thought that this is just an alternative, not the first choice.

Any idea?
