How to claim resources without a token?

That's how Mutex.lock works in v0.4.0; you don't need a token -- the Threshold token is gone in v0.4.0.

I think I need a way to access a uart resource in the init function

This is not possible. Resource proxies (the structs that implement the Mutex trait) are tied to the stack frame of the task that owns them; they are not Send, either, so even if you could create one in init you would not be able to move into any task.

If you need fine-grained locks, i.e. a struct that contains a resource proxy, you'll have to write a generic struct (e.g. struct Foo<R> where R: Mutex<Data = u32> { resource: R, state: State } and re-instantiate it in every task where you need it.

Thanks, I'll take a look at mutexes. It'll be hard to do initialisation different, though.

I think the original question has been answer. If you have additional questions please open a new issue.
