Thanks for all - and thank you for the tip about openocd. It turns out that the lead I'm using - which is better quality than the
lead supplied - doesn't work very reliably on two of the machines I tried it on. On the laptop, it worked immediately and I was
able to see that it was attempting to boot a kernel and hanging. Reset: interrupted U-Boot successfully, and am now attempting a 
reinstall.

Thanks to all who have offered help: sorry to have caused the noise.

All the very best,

AndyC
