This is perfectly ok. I could not think of a better place to ask,
either.

It should still be there. At least I'm not aware that it was thrown out.

The standard firmware for the BDI2000 does not provide this feature.
But I know that Abatron provided such a solution as part of their
excellent support - within less than a day AFAIR.
I guess this solution is still available.

We encountered similar problems before; this is one of the very few
cases where I think that starting with a version of U-Boot that gets
loaded to RAM first actually makes sense.

You are welcome.
