Dear all 

  I have only a board of EP2C35 (Altera dev kit), but i don&#39;t known how to run the linux . i select the Cyclone dev kit or stratixii config.but when i select the Upload the kernel  i find the next message   ------------------------------------------------ Microtronix Linux Extensions Version 1.4, Built June 20, 2005 ------------------------------------------------ (note: only Altera-provided flash components will work, since install.ptf was not found.

I have know the "upload" can&#39;t work in the NIOSII 5.1 . so I must use the Flash Programmer.

Hi Alex, 

 You are correct; the nios2-flash-programmer command syntax is changed in 5.1.  1) Start a Nios II SDK Shell (SOPC builder --> Tools --> Nios II SDK Shell)  2) At the CYGWIN command-line, type....  nios2-flash-programmer --base=0x0000000 {yourPath}/vmlinux.flash  If all goes well, uploading to the device should take a minute or so. Later, you can use exactly the same method to upload &#39;romfs.flash&#39; also.

In fact, if you&#39;re following the "Linux Quick Start Guide", you do all this not in SOPC builder, but in the Eclipse IDE. As such, there is no way to launch the SDK Shell from the Eclipse IDE.  To fire up the Nios II SDK Shell, do this:  Start-->Programs-->Altera-->Nios II 5.1-->Nios II SDK Shell
