There are lots of past discussions on this topic. The 1st time you do an upload, XOD has to stop and download/install the appropriate AVR code. There is no indication in the status that this is happening, so people will often interrupt the process thinking something has gone wrong. Now they are left with a corrupt download or partial install of AVR and XOD does not catch the problem and cannot auto-recover from this state.

The easiest solution is probably just to re-install XOD, make sure you have an internet connection and try uploading a very simple program (like a single led node that turns on the built-in led) and let it run to completion. Future uploads will be much faster once AVR code has been downloaded/installed.

Note that this download/install will happen again the 1st upload after you switch to a different Arduino board.

A time enough to download ~100 MB. It could happen you’re stuck after the first interrupt, so you’ll have to clean the incomplete download manually or install the toolchain by hand. See [Can I manualy install the toolchain?](https://forum.xod.io/t/can-i-manualy-install-the-toolchain/319/2?u=nkrkv) for more details.
