Hi,
may you think I'm on the wrong list, no not :-)
I currently build my u-boot loader using the linaro tool chain 2013.09
and run into a problem with the support for JFFS2 where the linker report
VFP usage where u-boot using softfp for build.
compiler options: -ffixed-r9 -msoft-float
Please try option -marm -march=armv4t -mfloat-abi=soft
I think its not a matter of the -m options the u-boot build call them expect the
-mfloat-abi=soft

By default the libraries in arm-linux-gnueabihf toolchain is hard

when I use

may someone have a closer look into it?
