This is from Galaxy J6:
memory at 40000000 {
device_type = "memory";
reg = <0x0 0x40000000 0x3d800000>;
};
memory at 80000000 {
device_type = "memory";
reg = <0x0 0x80000000 0x40000000>;
};
changes to
memory at 40000000 {
device_type = "memory";
reg = <0x0 0x40000000 0x3d800000>,
<0x0 0x80000000 0x7d800000>;
};
I assume I have changed it correctly? `free -h` displays the full
and correct memory capacity.
