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. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
