I am attempting to install the Nios2 Linux development tools on a Centos 6.3 based system.
I am somewhat confused by the instructions (on alteras wiki: Install_Nios_II_Linux). They indicate that the test-nios2 branch is the current branch of the kernel, but the nios2-linux-20100621.tar doesn't come automatically configured for this branch. The instructions also indicate that the current kernel uses the Devicetree approach to configuring the kernel for hardware, though, if I build with the test-nios2 branch, I have to use the vendor_hwselect mechanism Can someone tell me what the current branch is (test-nios2 or nios2mmu under linux-2.6 and test-nios2 or trunk under uClinux-dist) and what the current hardware customization mechanism is (vendor_hwselect, devicetree or sopc generated header)? Also, assuming that the current hardware customization is something other than vendor_hwselect, how do I configure things to get it? Thanks in advance. I'm trying to get ready to use this in a college class that starts at the end of September. D.W. Lynn For reference, Here is what I did, working from the Install_Nios_II_Linux instructions on the wiki, specifically using nios2-linux-20100621.tar. The tool-chain build step first complained: /home/lynnd/nios2-linux/toolchain-build/u-boot.mk:11: Board not defined! Using EP1S10 as default. and later fails with the following: ... home/lynnd/nios2-linux/uClibc' make[2]: `conf' is up to date. CC libpthread/linuxthreads.old/cancel.o In file included from ./include/sys/syscall.h:34, from libpthread/linuxthreads.old/restart.h:16, from libpthread/linuxthreads.old/cancel.c:23: ./include/bits/syscalls.h:10:23: asm/traps.h: No such file or directory make[1]: *** [libpthread/linuxthreads.old/cancel.o] Error 1 make[1]: Leaving directory `/home/lynnd/nios2-linux/uClibc' make: *** [/home/lynnd/nios2-linux/toolchain-build/../uClibc/lib/libc.a] Error 2 So, I switched to the prebuild binary toolchain, which worked. Then I attempted to make the kernel per the instructions using the make menuconfig process. There were lots of undefaulted options. On the final kernel make, I had to do "make CROSS-COMPILE=nios2-linux- since the default CROSS_COMPILE was nios2-linux-gnu- and that's not how the binary toolchain installed and I couldn't find the CROSS_COMPILE option in make menuconfig kernel customization. However, I still got the following error: /home/lynnd/nios2-linux/linux-2.6/arch/nios2/kernel/entry.S: Assembler messages: /home/lynnd/nios2-linux/linux-2.6/arch/nios2/kernel/entry.S:542: Error: expecting control register /home/lynnd/nios2-linux/linux-2.6/arch/nios2/kernel/entry.S:542: Error: unknown register r6 make[3]: *** [arch/nios2/kernel/entry.o] Error 1 Following some hints elsewhere in the forum, I removed the nios2-linux/ directory completely and untarred nios2-linux-20100621.tar again (to start fresh). Then, before doing the ./checkout step, I did "git checkout test-nios2 -f" in both the uClinux and the linux-2.6 directories. Now the kernel make process succeeds even though it uses the vendor_hwselect mechanism. Note that the documentation for Devicetree (linux-2.6/Documentation/devicetree) does not exist in the test-nios2 branch and make menuconfig in this branch does not give options for using the Device tree approach (that I could find).コピーされたリンク

--- Quote Start --- Hi, This is a long term bug which is caused by using the compiler optimization algorithm. ____ilog2_NaN is inserted to check the sanity of variable, and this function is eliminated during the optimization in normal situations, so the kernal will not call it actually. But it seems that they have finally given up this doubtful method. http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1340693.html So, please try to delete the function ____ilog2_NaN from the file 'include/linux/log2.h' according to the diff contents which is written in the last part of its mail. Kazu --- Quote End --- Thanks a lot, now I'm getting somewhere. I got a new compiler error that I think is something with the linker.

--- Quote Start --- Hi, Of course, you did . Copying 'sc.cfg' file is written in the 'rc' script file or somewhere ? Kazu --- Quote End --- It's the Makefile that assumes the sc.cfg and syslog.conf I don't know what do to about it. If I remove those two variables then it builds, but they should be somewhere shouldn't they? The other changes was because of deprecation in Perl about define statement and a header in serve_image.c that I had to comment out but I don't know what I'm doing.

Hi,
--- Quote Start --- It's the Makefile that assumes the sc.cfg and syslog.conf I don't know what do to about it. If I remove those two variables then it builds, but they should be somewhere shouldn't they? The other changes was because of deprecation in Perl about define statement and a header in serve_image.c that I had to comment out but I don't know what I'm doing. --- Quote End --- The files which are indicated by the tag ETC_FILES-y#
ETC_FILES-y =
filesystems group issue mdev.conf mime.types modprobe.conf motd
passwd profile rc TZ nsswitch.conf syslog.conf sc.cfg
are copied from your /nios2-linux/uClinux-dist/vendors/Altera/common directory ro /etc. #
for f in $(ETC_FILES-y) ; do
$(ROMFSINST) ../common/$$f /etc/$$f ;
done ;
So you must create the 'syslog.conf' file (which is used for rsyslogd) and 'sc.cfg' (I don't know what's this). And you have 4 errors which are caused by your 'rc' script file. 1) ifconfig: SIOCSIFADDR: No such device ifconfig: SIOCSIFADDR: No such device are caused by the lines 86 and 87. # Set up eth1 IP address
ifconfig eth0 192.168.11.4 up
ifconfig eth1 192.168.1.4 up
2) cp: can't stat '/etc/sc.cfg': No such file or directory is caused by the line 93. # Move SoftClock config file to where it is accessed by application, location is hardcoded in application
cp /etc/sc.cfg /var/log
3) insmod: can't insert '/usr/sbin/fpga.ko': No such file or directory Usage: mknod [-m MODE] NAME TYPE MAJOR MINOR are caused by the lines 96 and 101. # Set up device driver, insert kernel module
insmod /usr/sbin/fpga.ko# create device node using major number /proc/devices table
CURRWD=`pwd`
cd /dev
MAJOR_NUM=$(awk 'BEGIN {FS=" "}; {if ($2 == "fpgasymm") print $1;}' /proc/devices)
mknod -m=777 fpgasymm c $MAJOR_NUM 0
cd $CURRWD 4) sh: can't execute 'rsyslogd': No such file or directory is caused by the line 105. # start rsyslogd daemon
rsyslogd -n -m0 -f /etc/syslog.conf &
If you don't require these, please delete or comment out those lines and recompile the kernel. Kazu
