erreur compiling Linux on Neek using neek_ocm_spi_mmu.zip

[Altera_Forum]

Hi guys, 

I have a problem in the compilation of linux with MMU on my NEEK. I have followed these steps. 1) www.niosftp.com/pub/linux/nios2-linux-20090929.tar 2) extract and checkout 3) setup the good path to toolchain-mmu/x86-linux2/bin 4) make menuconfig with "Default all settings" 5) make and it completly compile until the end and the creation of the image.  Then now i want to compile it for my neek. So 1) www.niosftp.com/pub/boards/neek/neek_ocm_spi_mmu.zip and extract 2) with n2sdk (installed on my Centos5) i ran  sopc-create-header-files --single custom_fpga.h 3) I copy it to the good location in linux-2.6/arch/nios2/include/asm 4) make menuconfig and select "Customize Kernel Settings" in order to select my custom_fpga in the nest screen. 5) I didn't modify anything else in the config 6) make and it makes error.   (it is a translation from french)  ... LD fs/proc/proc.o LD fs/proc/build-in.o LD fs/build-in.o make[2]: *** wait: No child process. Stop make[1]: *** [sub-make] Erreur 2 make[1]: going out of the directory /home/Adrien/nios2-linux/linux-2.6 make: *** [linux] Erreur 1  Do you have any idea ?

Hi.  

I just have used another harware. This one : http://www.nioswiki.com/@api/deki/files/296/=neek_web_server_mmu.zip This is the exemple hardware on the page  http://www.nioswiki.com/linux/creating_a_nios_ii_design_with_an_mmu Then i follow the same step (except that i did not run sopc-create-header-files because custom_fpga.h was allready in the directory) And there is no error at all. All the images have been generated.  Why did I have errors with the previous hardware ?

Please unselect altera tse net driver, and select ethoc for neek_ocm_spi_mmu.

Is it in the "Customize Kernel Settings" ? I have not find ethoc and tse net driver.

 Device Drivers -->Network device support ─> [*] Network device support [*] Ethernet (10 or 100Mbit) The new Kernel mainline driver could be used for OpenCores MAC (nios2-test or unstable-nios2mmu branch)    [*] OpenCores 10/100 Mbps Ethernet MAC support [ ]Altera Triple Speed Ethernet MAC support(SLS)

Ok 

 | +  [*] Network device support ---> | | | +  [*] Ethernet (10 or 100Mbit) ---> | | | | | + < > Altera Triple Speed Ethernet Mac Support (SLS) | | | | | + <*> OpenCores 10/100 Mbps Ethernet MAC Support  So just invert these two selections. Now it compiles without errors. But it do not start after nios2-terminal while the previous hardware (neek web server mmu) et the previous kernel configuration, the normal booting messages appears.

Please make sure you use the correct sof. There is prebuild image for your try out, and related config files in the u-boot page,

Ok. It works ! 

 My problem was that I did not have regenerated the file custom_fpga.h (with sopc-create-header-files) includes in neek_ocm_spi_mmu.zip (nor from www.niosftp.com (http://www.niosftp.com) nor from www.nioswiki.com) (And actually they are the the same hardware).
