Description

just seek to 1u64 and type x:

$ r2 -qc 'x@1u64' --
$ r2 -qc 'pd 3@1u64' --
            0xffffffffffffffff      invalid
            0x00000000      invalid
            0x00000001      invalid
$

Contributor guide

Research direction
Investigate the IO subsystem in radare2 to understand how seeking to address 0x1u64 is handled and why it produces invalid output. Look for existing circular buffer support or the need to add an option to make IO circular.
