I built my image from these instructions, and on my Beaglebone AI with 1GB of RAM, /proc/meminfo says “624984 kB”.
So, what’s consuming the other 413M? Can I get some of that back? Thanks.
By default, it is reserved for the C66/EVE processors. There has been much discussion about making it more dynamically allocatable, but, for now, it would require editing the device tree.
In specific, these lines would need to be removed or marked “disabled” by an overlay: https://github.com/beagleboard/BeagleBoard-DeviceTrees/blob/2d1271702ce962160fe3a632ebee394207e2714b/src/arm/am5729-beagleboneai.dts#L38-L101
Due to a lack of foresight, the nodes don’t have labels, which makes creating an overlay a bit more difficult.
In the default image, you can go to /opt/source/dtb-4.14-ti, edit src/arm/am5729-beagleboneai.dts to remove those lines, make, sudo make install and reboot and you should get all of the memory back.
make, sudo make install and reboot and you should get all of the memory back.
what or where should I make and sudo make install?
Im not a developer…
best regards
