Use the hard TEMAC. > 2) Linux > I'd like to build my kernel and filesystem myself. But which way to go? > Using OE, buildroot, ELDK... > Can you please provide some starting points for me? I've got buildroot working; it's probably the simplest for building from scratch. ELDK works well too. http://wiki.secretlab.ca/index.php/Linux_on_Xilinx_Virtex > > 3) Boot-Concept > The Mini-Module had only 4MB Flash. Is this enough for a root-fs? It's tight, but doable. You kernel image will be somewhere around 1 to 1.5 MB. Depends on how big your application is. Cheers, g. -- Grant Likely, B.Sc., P.Eng.
