Hi All,
I''m new to u-boot and I have a question:
I want to compile u-boot for a MPC8272ADS board on a Sun with the gcc cross-compiler.
In the u-boot README it says that I have to change the CROSS_COMPILE definition.
What do I change it to in this case?
Thanks,
Stan Kuciej

You set it to be the name of the cross compiling GCC binary prefix. Likely, something like "sparc-unknown-linux-ppc-". For example, I have a meticulously named toolchain environment that supplies a cross compiler like this:

    % make CROSS_COMPILE=/_TOOLS_/dist/gnu-gcc-3.3-e500-branch-20040127-binutils-2.14-powerpc-unknown-linux-gnuspe/i686-pc-linux2.4/bin/powerpc-unknown-linux-gnuspe-

Since I don't know what your toolchain looks like, you are going to have to figure out how that maps to your tools, I'm afraid...

HTH, though,

Wat exactly is the name of this cross compiler?

I don't know the name of your cross compiler, so how can I tell?

Best regards,
