Honored ContributorProblems with installing Nios2 Linux
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).32 Replies
Altera_Forum--- 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/[email protected]/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.

So you must create the 'syslog.conf' file (which is used for rsyslogd) and 'sc.cfg' (I don't know what's this).
