I'm trying to install FreeBSD on a Linksys NSLU2

Hi,

I'm trying to install FreeBSD on a Linksys NSLU2, and hopefully in the end being able to boot it from a usbstick. I am not very skilled in FreeBSD. At least it seems this man have gotten things to work to some extent. I've briefly read his article on slimming down the kernelconfig-file. This is how far I've come

I downloaded his slimmed down kernelconfig file named 'NSLU2'. I placed it in some directory on another amd64 machine I own and symlinked it to /usr/src, then from /usr/src I ran 'make buildkernel KERNCONF=NSLU2', as it says in the handbook. But I got an error saying it cannot find the configfil named 'NSLU2'. What to do now?

The config needs to go in /usr/src/sys/arm/conf.

I still got these error messages (the same ones as before):

Code: 
[root@one /usr/src/sys/arm/conf]# make buildkernel KERNCONF=NSLU2
make: don't know how to make buildkernel. Stop
[root@stack /usr/src/sys/arm/conf]# cd /usr/src
[root@stack /usr/src]# make buildkernel KERNCONF=NSLU2
ERROR: Missing kernel configuration file(s) (NSLU2).
*** Error code 1

Stop in /usr/src.
*** Error code 1

[root@one /usr/src]#
 
If you need to build a kernel for a different platform (i.e. cross-compile), you'll have to specify that platform. Try adding TARGET=arm to that make command. I have no idea whether 'arm' is the correct platform, but I'm sure aragon does.
 
I haven't played with any arm stuff personally, but the page rusma linked to does mention the cross-compiling bits:

Code: 
setenv TARGET arm
setenv MAKEOBJDIRPREFIX /tmp/$USER/obj
setenv TARGET_BIG_ENDIAN t
setenv TARGET_CPU_TYPE xscale

rusma, those environment variables are important. They tell FreeBSD's build system to compile everything for the arm architecture. Without them the build system will compile for your native architecture.

My native architecture is amd64. Is it not enough how do I add these are they not specified already in the configfile?
 
Ok,
Now I've tried out those enviroment variables under bash shell:

Code: 
[root@freebsdvbox ~]# cd /usr/src/
[root@freebsdvbox /usr/src]# export TARGET=arm
[root@freebsdvbox /usr/src]# export MAKEOBJDIRPREFIX=/tmp/$USER/obj
[root@freebsdvbox /usr/src]# export TARGET_BIG_ENDIAN=t
[root@freebsdvbox /usr/src]# export TARGET_CPU_TYPE=xscale
[root@freebsdvbox /usr/src]# make KERNCONF=NSLU buildkernel

The source is the latest FREEBSD-CURRENT, updated today. What more enviroment variables have to be specified?
 
Not sure, but the errors you've pasted looked like they're caused by errors in the kernel config. Try fix those first.
 
I use bash, not tcsh, so setenv becomes export, and = is used instead of space.

So I "exported" each:
Code: 
export TARGET=arm
export MAKEOBJDIRPREFIX=/tmp/$USER/obj
export TARGET_BIG_ENDIAN=t
export TARGET_CPU_TYPE=xscale

But, still got error before the kernel started building itself. Should I post them too?

post your errors and kernel config too.

NSLU2.txt: standard NSLU2-config from /usr/src/sys/arm/conf/ (aka. the kernel config)
nslu2error.txt: output from build (both standrad error and standard output)
