hmmm, never saw this. I have a console connected, the moment the script
started, on the console I got:

	U-Boot SPL 2016.01 (Jun 19 2017 - 00:32:19)
	DRAM: 512 MiB
	CPU: 1008000000Hz, AXI/AHB/APB: 3/2/2
	Trying to boot from

which looks right, the date+time are good.

Where I started the script I get:

	# UBI_IMAGE=core-image-full-cmdline-chip.ubi
	# tmp-glibc/deploy/images/chip/flash_CHIP_board.sh

I don't get any LED flashing, and nothing other than what I've pasted above on
the console.

Rebooting the board after flashing outside of FEL mode simply boots the
previous u-boot and image.

Any thoughts?
