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:"

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..
