I am using piCore-7.0rc1 with my RPI2 (Arm7). I enter "tce-load -i ./gpm.tcz" (I have that on my USB flash disk) and then "gpm -m /dev/psaux -t imps2 -R". On Corelinux the text mouse would then move over the screen.
However, it does not do that on piCore. What needs to be done to support the mouse with gpm?
