Has anyone tried the ai MNIST example with gap_sdk version 3.9.1? For me, everything works fine until the point where the image is flashed to the deck, at which point it just stalls. I attached the full output of running "make clean_train clean all run"
I am using the J-Link debugger, but I don't think its the issue.
The reason I want to use version 3.9.1 instead of 3.8.1 is that nntool has many bug fixes and improvements in this version. For instance, the sigmoid activation function is not working in 3.8.

That is a good point. We haven't updated the examples yet to 3.9.1 but we should probably go and take a look at it soon. We have [an issue on the repository](https://github.com/bitcraze/AIdeck_examples/issues/41) already open for this, so let's perhaps discuss further there.
