New tutorial: How to rapidly build and test Espruino for banglejs2 about espruinodocs HOT 2 CLOSED

Hi,

yes, this would be a good guide. I think https://github.com/espruino/Espruino/blob/master/README_Building.md#super-easy-github-method is probably what you need though.

To perform a DFU update on an nRF52 device, you need to unzip the BOARDNAME.zip file and then the zip file inside that called espruino_2vXX.YY_boardname.zip is the one you need to use for the firmware updates. On MacOS it may not be immediately apparent that the thing in BOARDNAME.zip named espruino_2vXX.YY_boardname is another zip file, and not a folder.

So linking to that from the tutorial might be good - I think that answers your second question.

Thanks for the links, that helped a lot! I am waiting to see if the two open PR's can be merged, then I should be ready with the tutorial :)
