[Buildroot] buildroot-2017.11.1 and cape manager for Beaglebone Black.

Hi all,

I'm working with that version of buildroot and trying to enable CAN 
buses. After a lot of reading and research I have concluded I need cape 
manager to enable the CAN buses using overlays, but I am not sure if 
cape manager is supported by kernel 4.4.41 which is the selected by 
default and I am not sure if my conclusion is right.

Could anyone to point me in the right direction?

TIA.

Carlos.

You don't need cape manager for the built-in CAN controllers of the BBB
or to use any CAN capes with external CAN controllers that the BBB
communicates with over SPI.
 
It's just a matter of adding some sections to your dts. You can do it with
an include to your main dts.
 
Here are some links for dts includes to the 4.4 mainline kernel to enable
the built-in CAN controllers. Just a little pin muxing. This assumes you
have the kernel modules enabled, which you probably do.
 
The cape manager stuff was never supported by mainline linux or even TI
linux kernels only the Beaglebone specific kernels. And it's not even
supported by the Beagleboard folks anymore.They have moved to a u-boot
approach.
 
Cape manager is a technological dead-end.

Thanks a lot, you have saved me. It's working and I owe to you a couple 
of beers :)
