I am a newbie to BF and uClinux and I'm working in Blackfin  BF526 platform for a DSP project. OS is going to be uClinux and i was wondering if you can direct me to some directive to jump start my project. If I could get a sample hello world project to show how to set thing, that would be very helpful.

I managed to setup toolchain and compile hello.c.

But I am getting the following error when I try 'make image':

debian:~/uClinux-dist# make image

any idea what could be wrong? I couldn't find 'romfs' folder in 'uclinux-dist'

thanks

you cant use `make image` if you havent actually compiled anything yet

also, you should not be building as root

I am following the instructions here:

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

I logged in as a user and trying to make menuconfig, but I am getting the following error:

if you dont have a basic compiler installed, then you havent installed any of the basic packages the documentation says to

please read:

I have already installed the blackfin toolchain which includes both 'bfin-linux-uclibc' and 'bfin-uclinux' folders.

Do I need to install any othere packages in addition to that to compile 'uClinux-dist' ?

Thanks Mike,

I installed all the missing packages and now I am able to run 'make xconfig' however, in the wiki page it is asking:

Select 'y' for Customize Kernel Setting and Customize Vendor/User Settings

I don't see that option (Customize Vendor/User Settings), I only see the following options and I already selected 'Customize Kernel Setting' :

--- Kernel is linux-2.6.x

--- Libc is    None

[ ] Default all settings (lose changes)

[ ] Customize Kernel Settings

[ ] Customize Application/Library Settings

[ ] Update Default Vendor Settings

Should I ignore it?

I got it to work, vendor setting shows on a separate line option.

Thanks
