[U-Boot-Users] loads command is not working

[U-Boot-Users] loads command is not working

[Vaibhav Hiremath]

Hi All,


Can anyone tell me how to test loads command?
I have tested loadb and loady command, and they are working fine.
While testing loads uboot console only displays message "Ready for loading
s-record file" but doing nothing.

I think I am testing this command with wrong procedure, I hav used
hyperterminal to test loadb and loady commands.

So please guide me to test this out.


Thanks in advance.

Thanks,
Vaibhav

The most reliable way is using "cu", see
http://www.denx.de/wiki/view/DULG/SystemSetup#Section_4.2.

YOu may have success with other terminal emulation  programs  if  you
adjust  timing correctly, but details are left as an exercise for the
reader. If you just need a working tool, use "cu".

Use "cu".

Just to make the list complete:
Linux Host:
minicom v2.2
http://alioth.debian.org/projects/minicom/

And for the most proprietary OS:
UTF-8 TeraTerm Pro with TTSSH2
http://sourceforge.jp/projects/ttssh2/
Yes the good old TeraTerm we've used long time
ago with our 300bps Modems is back!

And for monitoring every little detail of your serial port on
Windoze - Mark Russinobich's Portmon:

Uah... ugly link. :-(

Technically, it works fine. Propably, some don't
like the UI, which has a vi like flavour.
Well... it works for me. YMMV

The problem is not the interface, the problem is that minicom is 
unreliable.  I actually generally use it as the path of least 
resistance, but occasionally it messes me up.  I have used cu as well 
and should switch, but have not yet.

The typical problem I have with minicom is that the tty port gets messed 
up (baud rate, handshake, etc. is wrong) and minicom cannot recover it. 
  Minicom will tell you it is changing the port configuration (baud 
rate, for instance) and say that the baud rate is what you set it to, 
but it really isn't.  As you can imagine, this is very confusing and 
frustrating when the board you are connecting to appears to only put out 
garbage characters and trying all the common baud rates does not change 
anything.  It looks like there is a serious problem with the development 
board, but actually it is minicom.

Interestingly, I've never had a problem getting kermit to reset the port 
characteristics to a sane setting when this happens, and then minicom 
will behave again, for a while.

There is a reason for this section in the manual:
http://www.denx.de/wiki/view/DULG/SystemSetup#Section_4.4.

"cu" in probably not what you are looking  for.  I  use  it  only  on
boards  where  I  am stuck with S-Record download (usually to program
U-Boot instead of a proprietary bootloader that suppors only S-Record
download).

kermit is my tool of choice, too.

This is a known issue, bug or feature:

If you ran into a problem which is reproducable, please try to fix
it and/or contact the developers of minicom to get it fixed.

Hi Clemens,

Not exactly.  The above says "Minicom continues to use the original 
value unless you save the setup, then quit and restart minicom."  My 
experience is that changing the baud rate on the fly works, but 
sometimes the port gets into a funky state and minicom "loses control" 
of it.

Unfortunately, it is not reliably reproducible.  :-(  Pure speculation 
is that incoming serial (from powering up the attached development 
board) sometimes confuses the port and minicom doesn't use a big enough 
hammer to reset it.
