Interesting that [1] states it's possible, though...
With the dreamplug, I often load u-boot into RAM via the JTAG (0x0600000 and 0x0800000), and then 'resume 0x0600000'. Then use the u-boot running from 0x0600000 to burn the image to SPI flash from 0x0800000. But that's loaded via the JTAG, not from a running u-boot.
Yes, I do have a JTAG. And I have used openocd in the past to recover the plug, so I will try that method.
I think I posted instructions to this mailinglist a while ago about this. If you have the JTAG (it's only $35US), I would advise trying that.
Yes, I've seen that, too. However, I've also seen the instructions for doing it from within u-boot in the link I posted. Since they didn't work I thought it might be bug. Never thought that it wasn't supported and not supposed to work at all :)
