Hello Harald,
Season's greetings! I was on Christmas vacation and just back in office today.
Thank you for your time and patience to respond with the details of standard message structure of osmocom coding style.

I'm sorry, at this point I'm not compliant with that and surely require some effort on that front. Right now my priority was to make this piece of software work with Octasic Phy and I'm very close to that and will update you after the testing.

Right now the code is not very clean as I might not have followed osmocom coding rules and needs to be cleaned up. But I'm trying to share the OSMOBTS modifications with you. As I said I'm new to git, I'm just trying by going through some tutorials. 

I have local folder osmo-bts which was cloned from osmocom repo
git clone git://git.osmocom.org/osmo-bts.git

I then changed the branch to jolly/trx from master:
git checkout -b jolly/trx origin/jolly/trx

I then created my private branch:
git checkout -b jason-oct-phy

Then I have added all my changes into it.

I then added the modified files into git.
git add .

Then I commited the changes:
git commit -m "jason-oct-phy new branch - Initial commit"

Changed the author & email:
git config --global user.name "Jason"
git config --global user.email jason.anoop@gmail.com

updated the commit to reflect the above:
git commit --amend --reset-author

git log shows:
root@gsm-bss:/home/osmo-bts# git log 
commit 9bd1926c1e105844ce3e8d39234c6aec9259cc27

    jason-oct-phy new branch - Initial commit

I can see my branch active:
root@gsm-bss:/home/osmo-bts# git branch
* jason-oct-phy
  jolly/trx
  master

I see all my changes are commited:
root@gsm-bss:/home/osmo-bts# git status
# On branch jason-oct-phy
nothing to commit (working directory clean)

I can also see the diff between jolly/trx branch and my jason-oct-phy branch.
git diff jolly/trx jason-oct-phy

However, when I try to push my branch changes to the repo, I fail.
root@gsm-bss:/home/osmo-bts# git push -u origin jason-oct-phy
fatal: remote error: access denied or repository not exported: /osmo-bts.git

Could you please help me if I'm missing something? Why am I not able to push the changes? Thanks for your help in this regard.

Cheers!
Jason
