Quick start refers to non-existant RTEMS 5.1.0?

[Maxim Blinov]

Hi all,

I was just curious about RTEMS, and wanted to get a "Hello World"
running on a simulator. I was following the quick start guide here:

https://docs.rtems.org/branches/master/user/start/sources.html

where the tutorial talks about obtaining version 5.1.0 of the RTEMS
kernel. But this version doesn't seem to exist: The FTP links listed
don't work, and sure enough I can't find any tag or branch
corresponding to version 5.1.0 apart from one commit from 2017:

commit 4a14751879f61ba7a045a1fcc7ff485a88dcb51d
Author: Sebastian Huber <sebastian.huber at embedded-brains.de>
Date:   Tue Oct 17 13:44:22 2017 +0200

    Upgrade to 5.0.0

    Tool name will be "rtems5", e.g. arm-rtems5-gcc.

    Next release will 5.1.0.  Branch version after release will be 5.1.1.
    Next master will be 6.0.0.

Could someone please advise me on what version I should be using?

Best Regards,
Maxim
