Does anyone know where I can find a bf526 ezbrd defconfig? All I see is precompiled images or the raw source with no default config for the bf526.

Thanks,

Nathan

all defconfigs are in the standard linux location: arch/$(arch)/configs/

Please forgive the silly question, but I'm new to the uC distribution. The source I got doesn't have an arch/ directory. It does have something called linux-2.6.x though. Am I supposed to supply the standard kernel in there?

Mine was empty by default. I got it from git://sources.blackfin.uclinux.org/git/readonly-mirrors/uclinux-dist.git as instructed by the BlackfinKoop. Is this normal? Should I try from scratch?

If I manually get the linux source from the linux git and put it in the linux-2.6.x/ then copy the BF526-EZBRD_defconfig into vendors/AnalogDevices/BF526-EZBRD as config.linux-2.6.x I can start compiling, but with quite a few new config options. Then it eventually crashes out with an error like so:

i dont know what instructions you read, but they did not tell you to download the git tree. use the 2010R1 release.

your log snippet does not contain the actual error. you need to scroll back up to find out where things are actually going wrong, or run `make single`.

Alright, I wanted to do as much of this from source up as possible. My default reaction was to get everything from their repositories so nothing was prebuilt. This has proven quite difficult and I've settled for a prebuilt toolchain, prebuilt uClibc, prebuilt u-boot-uart.ldr, and now uClinux.

Regardless, I downloaded the 2010R1 release (it did have the linux-2.6.x source as you mentioned) and started the build. It crashed in the same spot.

Looks like a mismatch in priveleges. Am I supposed to be doing the make as root?

If I run 'make single' I get a completely different error:

that is a harmless warning and can be ignored. it isnt the actual error preventing you from building things.

Assuming you are referring to the first error from the regular 'make' not the error from the 'make single' I don't know what to say. It tells me the error and stops compiling. No /images directory ever shows up.

Are you familiar witn the bf526 ezbrd? Most of the documentation I'm finding talks about loading a uImage over tftp, but I can't find anything about loading it from onboard. It'd be nice to have a stand alone board with non-volatile root filesystem.

Any other thoughts on compiling the kernel? I still can't get the build to get far enough to result in an /images directory.

you need to install development packages like the documentation explains:

docs.blackfin.uclinux.org/doku.php?id=installing_linux

those lzo files need to be in your host system
