I am using linux ubuntu 16.04 i686 bit os. I understand 32 bit version are not support for above 4.9 cross compiler as per documentation.
technomed@technomed:~$ /home/technomed/gcc-linaro/bin/arm-linux-gnueabihf-gcc --version
bash: /home/technomed/gcc-linaro/bin/arm-linux-gnueabihf-gcc: cannot execute binary file: Exec format error
I got error on both 5.2 and 6.2 cross compiler. Is it possible to compile linux image v2.8 using gcc 4.9 cross compiler in 32 bit ubuntu. thanks for your help.
