[yocto] Antwort: Re: How to set the sysroot toolchain to hard float

hej

@find out:
transfer a build package into the evalboard and try to install it. I am 
using deb packages. dpkg gives me an error  because of architecture.

@print configuration output:

@TOOLCHAIN_OPTIONS: Where these are set in custom layers(like meta-atmel)?

How did you find that out ? can you send your build configuration output
that bitbake prints when starting the build ?
secondly, TOOLCHAIN_OPTIONS is what decides this ABI
so when you use CC and CXX and friends, the right thing happens since it
will be appending TOOLCHAIN_OPTIONS to these vars. but if you use bare
cross compiler that will default to soft-float
