Hi, 

 I was working with trunk branch and the nios2install is for test-nios2 branch, so i have read something about git tool  0: internet connected 1: switch to nios2-test  at git repo ../uClinux-dist/  $git branch -l   test-nios2 * trunk $git checkout test-nios2 $git branch -l * test-nios2  trunk  2 : update  run ../nios2-linux/update  3: uClinux-dist/make menuconfig  ERROR: there is not any rule for target config.arch building  and i can see tha there is a link file named config.arch linked to vendors/Altera/nios2nommu/config.arch  ¿?  THANKS IN ADVANCE

[Altera_Forum]

Hi, 

 i can see that there is not a /vendors/Altera/nios2nommu/conf.arch file ........  why ? is wrong the link?  Now, i am confused about nios2-linux versions  which i need 20090929 or 20090730?  wget http://www.niosftp.com/pub/linux/nios2-linux-20090929.tar wget http://www.niosftp.com/pub/uclinux/nios2-linux-20090730.tar  the wiki mixed the 2 versions  I am going to remove the new version and install the old version 20090730   Some aclaration please?  THANKS IN ADVANCE

Hi, 

 i have reinstall the nios2-linux-20090929  but now BEFORE run makes..... i have SWITCHED git branch to NIOS2-TEST branch  and i get my first kernel image.  bye

[Altera_Forum]

hi candido, 

can u explain "SWITCHED git branch to NIOS2-TEST branch" more detail? did u follow the steps in repply# 2? i really need this thanks!

[Altera_Forum]

Hi Nguyen Tien, 

 In reply# 2 you must select test-nios2 branch with the command: $git checkout test-nios2 after, you can test your branch -> $ git -l branch     bye

[Altera_Forum]

..more information 

 nios2-test is the nommu uclinux distribution  you must select test-nios2 branch on uclinux distribution directory and linux-2.6 kernel source directroy too  cd linux-2.6 git checkout test-nios2 cd uClinux-dist git checkout test-nios2  Cándido

[Altera_Forum]

hi Cándido, 

thank you, now I can build the image :D

[Altera_Forum]

Thanks a lot. 

I was also able to make nios2-linux-20100621.tar to work using these instructions. I have verified it on NEEK. I will confirm stratixIV_4sgx230 when done.

[Altera_Forum]

Hello,Candido.I do what you told,but I also got a error.I changed the branch,when I make the image,there is a error:

Hi, 

 there is a similar post in http://www.alteraforum.com/forum/showthread.php?t=20200   can you conncect with him  andido

[Altera_Forum]

I am sorry,I can not connect with him.He fied that problem one year ago,and maybe he is so busy that he can not come thr forum.

[Altera_Forum]

hello i am with the same problem you had, same computer specs also. 

 Can't run this 2 : update  run ../nios2-linux/update  can anybody help? Thanks

[Altera_Forum]

Are you sure you were able to do the switch. To me it seems like you are still using the mmu branch.

[Altera_Forum]

Ok, now i am getting an error like "Unable to verify adress between (some adress) and (some adress)" after downloading my image to my board. 

 ANy tips? Thanks

[Altera_Forum]

You must select test-nios2 branch on uclinux distribution directory and linux-2.6 kernel source directroy too 

 cd linux-2.6 git checkout test-nios2 cd uClinux-dist git checkout test-nios2 ---------------------------------  I've done that,but:  [root@localhost uClinux-dist]# make menuconfig Makefile:63: config.arch: No such file or directory make: *** No rule to make target `config.arch'. Stop.  [root@localhost uClinux-dist]# make Makefile:63: config.arch: No such file or directory make: *** No rule to make target `config.arch'. Stop.  `config.arch' in the uClinux-dist folder is broken ... !!!
