Some places to start... There are two ways to do this. Start from the existing and pick away packages until you have what you want. Or, start from busybox/buildroot and add packages until you have what you want. The latter is the best way to get the smallest rootfs, but if you have 16M, you may be able to get there using the former. If you have the MontaVista tools, DevRocket includes a tool called Platform Image builder which allows you to select build your own rootfs, and it will handle all inter-package dependencies for you. > > Also, the current “top” (procps) utility on the board is version > 3.2.5; it doesn’t support displaying individual threads of a process; > > it only shows info about a process as a whole but not the thread. > Version 3.2.6 has that capability; does anyone know how we > > can get that version? Just download it and compile it. :) The development rootfs that ships with the DVEVM/DVSDK has the native compilers/linkers etc. to compile natively.
