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 (
http://www.rtems.com/wiki/index.php/supportedcpus) ? We already looked at the latest versions but the source doesn't seem to include it.
According to this website (link (
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 ? We are looking for some information concerning the porting of this RTOS on NIOS II.
