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
