Yes. With a smaller image (~90MB) the flash update worked. Maybe
another improvement for a v2 would be for the script to look at the
size of /full/path/to/UBI_IMAGE and issue a warning/error if it's too
I think the wording of what to expect on the host and over the serial
console could use some updating. Not to mention you say: "the status
LED on the CHIP board will flash 30 times per second..." which doesn't
seem to be the case, it looks more like the LED is toggled every 2
seconds (??), in any case, it's a lot slower than 30/sec.
