I have the same situation. I have a Lantronix EDS2100 which uses a ColdFire 5208 with 8 MB RAM and 8 MB flash. I was able to obtain more RAM by using the XIP option (enabled by a boot loader command) and by eliminating the RAM tmpfs (I had to edit a uClinux startup file). I do not know if these techniques are possible on your hardware. > How would shared libs solve the problem? All programs would share a single copy of uclibc. Presumably, your applications need it, so it would already be loaded when you run the ls command. I have no idea yet how to do this. > The problem is allocating memory for 'ls' data and not 'ls' itself. Is > this correct? It looks to me like it is coming from the ls command itself, not from the loader. > > Thanks > > Larry Baker US Geological Survey 650-329-5608 ba...@usgs.gov
