Also the code indicate that 2 x 1 sec sleep is used in this area, so please go through the above description when it comes to led experience during flashing. Another minor comment is that I believe you should update the UBI_IMAGE example in README to use the "default" meta-chip hwup image (chip-hwup-image-chip.ubi).

Indeed. The comment was intended to say that it flashes 30/min. Obviously flashing 30/sec would not be a very easy thing for people to spot.
I’ll work through the comments and submit V2. It will take me a few days.
Many thanks for the feedback.
