Hi all,
I’ve install arm-none-eabi-gcc toolchain and I am trying to load a
simple program on beagleboard. I created a flashing led program and
tried from U-boot to load it (through serial) in a memory location
(0x8e0000000) and execute it with go command but nothing happens.
Any ideas of what I am doing wrong?
Also when I am trying to compile a simple hello world program, the
compiler gives the following errors:

Thanks in advance.
