I want to install uClinux (2.6.9) on Cyclone 3 EP3C25F324C8, following the tutorial "http://scorpius.homelinux.org/~marc/nios2.html". 

When i arrive at the command "make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- hwselect SYSPTF=/home/nastri/nios/sopc.ptf" for the kernel configuration, there would be a list of hardware resources of my Nios system, but the list is empty (under "Please select a device to upload the kernel to:"). In the following it can be observed the problem in the Linux (Debian) shell.  "nastri@debian:~$ su Password:  root@debian:/home/nastri# export PATH=$PATH:/opt/nios2/bin root@debian:/home/nastri# cd linux-2.6.9 root@debian:/home/nastri/linux-2.6.9# make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- hwselect SYSPTF=/home/nastri/nios/sopc.ptf  no emulation specific options.  RUNNING hwselect  --- Please select which CPU you wish to build the kernel against:  (1) cpu - Class: altera_nios2 Type: s Version: 7.08120  Selection: 1  --- Please select a device to upload the kernel to:  Selection:"   Regards

Posting the same question multiple times won't get you more answers. Did you read the documents indicated by mschnell?

i met it too 

i just added a cfi and solved it i think 20070130 do not support spcs as good as cfi  minimum sopc modules for nios-ucLinux : nios2 f sdram (>8MBs) JTAG UART EPCS controller timer (full featured) CFI (even you don't have any flash memory in your board,and my DE0 don't,too,you just use it at your sopc )

Hi Sen_Han... maybe a bit late for a question to your respond - but worth a try :) 

 Yesterday I run into the same problem with my DE0-Nano: on a new uClinux download <make hwselect> asks for a CFI memory to upload the kernel to. In an older download version of uClinux this selection was not necessary (only CPU and execution device was asked for). So I will follow your advise and add a CFI to the SOPC-builder (Quartus II v10.1), I just wonder about the paramter settings and connections - any special set-up of this dummy/CFI ? Many thanks..
