29:40 - The reason the program crashed and went into UDF instructions is because on aarch64 you need to enable the floating point unit (FPU) before you can use it. I didn't do that and write_volatile seems to use an fmov instruction, which causes an exception if the FPU not enabled. The reason why it jumps into the UDF instructions at 0x200 is because we did not set up any exception handler yet.
