That doesn't mean that the documentationis obsolete. You  can  buy  a
Visio*  Debugger  if  you  like  (*), but this is a complete separate
product and has nothing to to with the RPXlite.

(*) IMHO your money is better spent if you buy a BDI2000 instead.

This cannot be done easily (*), and if  you  read  the  mailing  list
archive you will find why.

(*) "Not easily" means that you cannot do it if you have to  ask  why
    it's  not working or what needs to be done to get it working. And
    if you know these things, you will not do it because then  you'll
    also understand that it doesn't allow you to perform the test you
    are looking for.

This is writtenin the docs: burn it into flash, and reset the board.

No, you are NOT supposed to. There is not a single place in the  docs
which even faintly suggests this.

Just stick with the written documentation, and  follow  it  verbatim;
don't speculate.

You are confused. Running the "lilo" comand under Linux  has  nothing
to  do  with  running  the  "lilo"  boot  loader.  These  are totally
different programs.
