Firstly a quick note on version numbers, since this may cause confusion. eCos 2.0 was released for Nios II 1.0 service pack 1. The version of ecos that has been subsequently released for Nios II 1.1 incorporates a number of bug fixes and enhancments from the public eCos CVS repository. It is therefore not eCos 2.0. It hasn't been assigned an official release number by the eCos community, and so I refer to it simply as "eCos for Nios II 1.1".

I hope that's the version you are trying to run.

In any case, I'm guessing that you have assigned the wrong cpu name. The value passed to the --cpu option for nios2configtool is the name assigned to the processor in SOPC builder, rather than the type of processor. In all the Altera example designs the name is simply "cpu", so the command line you were looking for was probably:

nios2configtool --ptf=std_1s10.ptf --cpu=cpu
