OS Comparison Questions!

Hi Dan,

There's a gui for configuration (configtool) ... it provides the same functionality

as menuconfig/xconfig. If you can configure linux, you'll be able to figure out

eCos without much effort.

That depends on the developer ;-) ... it's all relative ... without an MMU and the

associated memory protection, you can access hardware directly and avoid

drivers altogether if you want (regardless of the OS).

You'll probably get better mileage with eCos (v. uClinux).

The Microtronix version is good, the enseirb stuff is garbage.

The Microtronix folks have done a very nice job and they continue to improve their

distribution. enseirb is unmaintained and unsupported garbage ... and only supports

Nios-32. If you go the uClinux route on Nios-II, stick with the Microtronix stuff,

it comes with periodic updates and an active forum where you can get help.

That's a great idea, please let us know when you have the site up and running!
