cc1: error: bad value (armv5) for -march= switch

Question

I am compiling u-boot for beagle bone black as per the steps mentioned on this link

http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-Bootloader:U-Boot

and getting the following error.

cc1: error: bad value (armv5) for -march= switch

can anyone help me in finding the reason for this error? I guess this is because of gcc not supporting armv7-a still not sure.

thanks, sumit

If you type the exact command shown on eewiki.net page, there would be a problem if you do not have env var CC set. I prefer the following, it assumes you have reasonably current install of arm-linux-gnueabi-gcc as your cross toolchain (adjust if you have something different)

export CROSS_COMPILE=arm-linux-gnueabi-
export ARCH=arm
make am335x_evm_config
make
