I have compiled the u-boot for beaglebone black but the only message that I can see is:
At elinux.org tutorial the expected result is some errors followed by the u-boot terminal available to use.
To build u-boot I've followed the steps:
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- distclean
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- am335x_evm_config
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
my SD Card is set like this:

Unfotunetly I confirmed that was a hardware issue :(
