Hi all, I have setup the toolchain with the settings from my previous email (-mcpu=cortex-a7 -mfpu=neon-vfpv4)
When I try to build the Linux kernel I get lots of warnings about conflicting toolchain options: arch/arm/kernel/elf.c:1:0: warning: switch -mcpu=cortex-a7 conflicts with -march=armv5t switch This is with OSELAS.Toolchain-2016.06.1, using arm-v7a-linux-gnueabihf. I am not sure where the -march=armv5t is coming from, since this is an arm-v7a toolchain. Also if I use -mcpu=cortex-a9 instead of cortex-a7, there are no warnings :-? Can anyone sehd some light ?
