Thanks Ron,
However, I too think GIT is Arcane :-) ...
Doing that (git checkout v3.15.0.0 -b tmp) creates a new local err...
branch, repo... called tmp.
How do I get the contents of the requested branch/tag up onto my machine?
It's not a branch, doing a git pull results in...
"
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.
git pull <remote> <branch>
If you wish to set tracking information for this branch you can do so with:
git branch --set-upstream-to=origin/<branch> tmp
"
Originally cloning the UHD repo results in one being on the Master
branch, i.e.
"git clone https://github.com/EttusResearch/uhd.git";
so how does one revert back to an earlier release please?
Hope you can help, sorry for my noob git knowledge!
Cheers,
Dave

Yes, it's not a problem. If you don't want to see the message, use:
git checkout v3.15.0.0 -b tmp
Also, you should never use the master branch of UHD. It's really a
development branch and could be unstable. Always use a release tag.
To see all the release tags:
git tag

That should be fine.
GIT is arcane. Others have more facility with it than I.

Thanks Marcus,
Sorry,, I know this isn't the place, but when i check out a version
I get "detached head...".
I also don't want to check anything back in, do I ignore this (I've
never understood what detached head means, even after looking it up!).
Cheers,
Dave

Hi,
I have just installed the latest "master" branch of UHD (4.0.0.0).
If an overrun occurs during sampling, sampling does not continue
thereafter.
I noticed this with uhd_fft, which hangs with rates over 8MHz, and
also rx_samples_to_file:

OGot an overflow indication. Please consider the following:
Your write medium must sustain a rate of 160.000000MB/s.
Dropped samples will not be written to the file.
Please modify this example for your purposes.
This message will not appear again.

Done!
Any ideas please?
Should I be using the master branch, if not how do I checkout a
stable branch ?
Thanks,
Dave
You can get a list of tagged versions using:
git tag
Try again with:
git checkout v3.15.0.0
Sometimes when the overruns are persistent and at very high rates,
the software is unable to recover, because so much information has been
dropped, any recovery procedure would be roughly as drastic as
having to re-start.
