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

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