This means your code took an exception (and there's
no RAM at the low address where the vector table is
by default). Try "-d in_asm,exec,int" to get a better idea
of what's being executed.

Also, where do you expect the output from that printf
to be going? Does your gcc/bare metal libc write to
the UART? How does it know what address the UART is?
If it's expecting to do semihosting for output, then you're
running into the fact that we don't implement semihosting
for AArch64 yet.
