No, I'd rather have it removed completely. It doesn't belong in a boot
loader which main goal was to be simple.

Say 99.99% of all cases.

This is where a diagnostics tool comes in handy. Make a standalone
diagnostics tool that can be downloaded with "download kernel". Now
type "boot", and voila, you're running the diagnostics tool.

- blob commands are simple. "download krnl" can be easily retyped as
  "download kernel".
- Several commands in a row almost never happens and if it happens it
  doesn't justify a command line history. The longest command sequence
  I know is "download kernel ; flash kernel ; download ramdisk ; flash
  ramdisk" but that is scriptable as Wookey showed before.

OK, what about this:

We keep blob simple: no command line editor, no diagnostics tools.
Instead, we add a directory diag, in which we create a separate
diagnostics tools that can be loaded by blob. Blob and diag could share
quite some code (serial ports, command line, etc), but apart from that
they are independent. Diag can get more features needed for
diagnostics, but blob remains simple. Deal?

cmd line hist etc

[<sch...@t-...>]

Hi all,
well, ok then. From your comments I assume that I'll have to put this code
under a #ifdef and make it a compile-time option.

Please do understand my arguments, tough:
- blob is a bootloader, yes. Most of the time only loads the kernel in a
specified (quick) way, nothing else.

- when one gets a defective board from a customer, blob _could_ be used
as a diagnosis tool as well. I do not want to have first a special blob version
flashed, because then i'd have to change the system in order to check it. I
want to test the board as it is, right then when i get it. I could even
instruct a technican via phone, specially useful when the board is somewhere in
brazil and a machine does not work because of your board not running (which ist
exactly what will happen, think of murphy's law).

- a command line history is rather handy if you have to issue
several commands in a row and misspelled one

- that's why i keep adding test/diagnosis commands, because i _know_ i will need
exactly these commands later for customer support, because i need them _now_ to
get our new board running.

Does this sound reasonable, or am i completly wrong?

I don't think it should be removed though. As long as there's a
configure option not to compile this in. In that case, those who want a
stripped down bootloader can have one and rest in peace that there's no
bloated code and those who wants a bells & whistles boot loader can also
have one (:

Seconded. What *would* be useful, though, is either auto-completion

Why would we need this at all? Blob is a bootloader, not a shell.
