Altera NIOS II

[Aurélien LIBERT]

Hi,

We are two students working on a project about a signal treatment
application running on an FPGA, the Altera Development Board. We would like
to use RTEMS on the NIOS II architecture. Is there a RTEMS version including
a porting on NIOS II as stated on the website ? We already looked at the
latest versions but the source doesn't seem to include it.

According to this website (http://www.ixo.de/info/rtems_nios2/), someone has
already worked on the porting. We asked him why nios II is no more supported
by rtems. Here is his reply :

So, is the porting possible and which version of RTEMS should we use ?
