What's the call?

It has been a few years since ASA. But... I believe a BR cannot back away from advancing to 1st (can stop but cannot back-up).

True, but only when the batter-runner is attempting to avoid or delay a tag. No tag is possible on a walk, so this rule does not apply.

Sounds like the runner gave up his opportunity to advance and should have been called out when he first abandoned any effort to advance.

See my answer above. The runner is not out for giving up or for abandoning this attempt to advance - ASA does not have that rule. He would have been out, though, for entering the bench area (fast pitch). The ASA rule is virtually the same as the FED rule you quoted.
