@matthewelse hey man, I'm going to be having a crack at playing with some bootloader stuff over the next few weeks, was hoping to ask you a couple of questions.

First of all, should the helloworld.hex within microbit-bootloader\tests actually display hello world? Or was it named that with future aspirations? If it was, did you get a chance to take a closer look at it?

Ah awesome, I think it just scrolls Hello World across the screen. Tbh the content of the hex file isn't as important as the upload working.

So, essentially the point I got to was being able to upload a hex file from a node script running on my laptop to the device and then run the contents of the hex file.

The issues that arose were:

  1. The upload only worked if there was not an existing application running alongside the bootloader.
  2. I haven't managed to successfully upload a file with the official micro:bit app

I don't think that there is a large amount of work left, but the main reason work has stalled on this was that I was really struggling to figure out what was going wrong. If you had any insight about what's causing the problems, that would be great. In terms of the test, there's nothing particularly exciting there.
