I am trying to download version 22.214.171.124 of this compiler, but it looks like the link is broken to download previous versions.
Here is how this error can be reproduced:
1. Go to this page MSP430-GCC-OPENSOURCE IDE, configuration, compiler or debugger | TI.com
2. Under "downloads", click the link to "view all versions".
Rather than redirecting to previous versions of the compiler, the link redirects to itself.
Please note that Marko created a thread for this issue about 6 months ago in this post:
Unfortunately, the thread has been locked and it appears the issue was not resolved.
