Hi,

Could you please provide the btmon HCI logs?

Hi Zephyr team,

We can find this issue on nRF51 DK and our custom board with zephyr source code(samples/bluetooth/hci_uart). Could you give us your advice on how to solve this issue?

Hi Ryan Erickson,

We use zephyr source code(samples/bluetooth/hci_uart) , and type following commands:

After then , we can find out device(named “2019bt”) in our phone , and we can pair it.

But “2019bt” will be disconnected after about two second at connected.

Could you give us some suggestions

Thank  You.

Hi Carles,

And thank you very much for the very quick answer.

I have installed git version 2.20.1 on my Windows and for some reason git doesn't add the path of its binary folder to the PATH environment variable.

After manually adding the git path "C:\Program Files\Git\bin" everything works fine :-)
west can now be used to install zephyr and also update west by following the below commands from the getting started guide.

west init zephyrproject

cd zephyrproject

west update

It might be a good idea to add a note in the getting started guide, that you have to make sure the path for git is added to the Windows PATH environment variable to make it work in Windows.

Best regards,
Bo

Hi zephyr,

I am not able to install the latest zephyr on Windows following the getting started guide.

I have previously installed zephyr on Windows without any issues.
But following the latest getting started guide, where west is now used as a part of installing zephyr, I get some problems with west.

I have forced installation of west again, which can be seen on the first attached picture "clone zephyr using west.png".
In this picture, I then verify the west version, and finally try to install zephyr with west, as explained in the getting started guide.
The errors I get can be seen on this first picture.

Then I try another approach.
I manually clone zephyr to a location using git bash in Windows without any problems.
Then I again follow the getting started guide and create an empty folder named "zephyrproject".
I copy my manually cloned zephyr into this folder.
As seen on the second attached picture "clone zephyr manually and use west after.png", I now have a "zephyr" folder below "zephyrproject" as displayed by the dir command.
Then I use the west init command as explained in the getting started guide and get the same errors, which can also be seen on this second picture.

I hope you can help me fix this issue.

In Linux, everything works fine following the getting started and using west for installing zephyr :-)

Best regards,
Bo Kragelund

Quick update following some more testing I did. I hit the same "packed-not-aligned" issue on Fedora 29. I applied the same fix and subsequently hit another issue (see error below), which got resolved by cherry-picking another commit from Grub2 that's in their master but not in 2.02. Here is the diff that allowed be to build the GRUB2 boot loader image (not tested yet on real hardware):

Should I submit this to Zephyr (as a PR)?

Hi folks,

I am trying to build a GRUB2 bootloader image following these steps on a Clear Linux system (version 28230). I ran into the problem below (see output at [1]). That is a problem with gcc 8.x that has since been resolved upstream (but not in the 2.02 version used by Zephyr), I cherry-picked that change and applied it (see [2]), but now I'm running into a new, different issue:

Hi there,

Which version of Zephyr are you using? 1.13 or the latest master?

Thanks,
