uCLinux 2.6.12 in NIOS II-Microtronix IDE

Altera_Forum · ‎05-30-2006

I want to use NIOS II IDE under Windows to debug linux-2.6.12.

(It could be the same for other kernels)

I succeded to compile it under Linux and it works but I want to modify kernel for my applications.

nios ii ide :

I downloaded sources linux-2.6.12-0.2.tar.bz2.

I renamed it in the directory com.microtronix.nios2linux.kernel_1.4.0

linux-2.6.12 -----> linux-2.6.x.

I added : dos2unix $(depfile); in ./Makefile, ./scripts/Makefile.build, ./scripts/Makefile.lib

I didn't modify : depmod_opts := -b $(INSTALL_MOD_PATH)/lib/modules -r

Then, I created a new microtronix kernel project.

When I launched Configure kernel, nothing happens.

So I tried the command configure.bat in a SDK Shell

c:/quartus51/bin/cygwin/bin/bash.exe -c "source $QUARTUS_ROOTDIR/sopc_builder/bin/nios_sh; source $SOPC_KIT_NIOS2/user.bashrc; KERNEL_PROJECT=C:/christophe/Noyau/LinuxAdeosWin/kernel; make -C `cygpath -u c:/altera/kits/nios2_51/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_1

.4.0/linux-2.6.x/` O=`cygpath -u C:/christophe/Noyau/LinuxAdeosWin/kernel/build

` menuconfig; "

I've got this message of errors

[SOPC Builder]$ make menuconfig

no emulation specific options.

make: *** [menuconfig] Error 2

I did the same under NIOS II SDK Shell.

nios ii sdk shell

I copied .config and linux.ptf in my kernel directory.

I use the following commands, slightly different as linux ones.

>> make hwselect SYSPTF=./linux.ptf

>> make menuconfig

Linux Kernel v2.6.12-uc0 configuration window opens, and I can make my configuration.

------

* Is it possible to do all the configuration and build of linux-2.6.12 under NIOS II-Microtronix IDE?

* Which files do we have to modify?

* Is there a moan to use linux-2.6.12 instead of linux-2.6.x?

Thank you in advance for your help.

Look in the nios wiki and work on Linux, http://nioswiki.jot.com/wikihome/operating...ms/%c2%b5clinux (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux)

Thank you for your answer,

Yes, indeed. Linux is better to developp or modify kernel.

I would like to use NIOS II-Microtronix IDE because of the very efficient tool to debug include in it.

I would like to import kernel source and add breakpoints in differents files entry.S, main.c, watch and poll registers...

Could we do the same under Linux?

There is GDB for that purpose.

But I don't use them. I would prefer debug by print.
