Hi Wolfgang, Thanks for the reply.
> there might be better options than JFFS2... Yep, it was a choice of convenience and not something that will roll out just yet. Regardless of choice, this specific board will be very tight on flash space. > it has never been a good idea to install complete packages with all the (potention) dependencies these may pull in > If you know what you need and pick exactly the needed files only the result may be different What I tried to do was rather start from snmpd and work from there (by running it on the target and seeing what it was yelling about). Is there a more intelligent way of doing this (and therefore allowing customization)? My understanding is that the eldk has a compiled with such and such MIBs and such and such dependencies - take it as a whole or leave it. Am I wrong? > [compiling net-snmp] you don;t want to install the whole packages either. Of course, from source I can leave out much functionality that i don't require (v3, for example and support for MIBs other than the absolute basic). Thanks!
