[U-Boot-Users] srec download fail

[Thomas Brand]

Hi,

I'm trying to download the hello_world srec-sample to my Nios Stratix 
Board with cu. I get the following printout:

   DK1S10 > loads
   ## Ready for S-Record download ...
   ~>hello_world.srec
   1 R R R R R R R R R [timed out looking for echo]
   [connected]


my configuration:

   U-Boot 1.1.2 (May 24 2004 - 15:54:07)

   CPU: Nios-32 Rev. 3.3 (0x3038)
   Reg file size: 512 LO_LIMIT/HI_LIMIT: 1/30
   Board: Altera Nios 1S10 Development Kit
   Conf.: Microtronix LDK 2.0 (LDK2)
   In:    serial
   Out:   serial
   Err:   serial

It does not work with kermit either. The loadb cmd with kermit works fine.

Does anybody has a hint for me?
Thanks in advance.

Hi all NIOS developers/users,

this is the second error report related to download problems by using the 
serial line. AFAICR I had have trouble too some times ago; just I expact any 
serious error in the Nios port. Sadly, I'm really busy with other projects so 
I can't explore the reason for this problem in the next time. Is there 
anybody who can do this job?


Best regards,
Stephan

Is "loads_echo" set to 1 in your environment?

S-Record download with kermit is not supposed to work.

I don;t think there is anything wrong with the NIOS port, as the O.P.
reports that "loadb" with Kermit  is  working  fine,  which  is  more
stressing on the serial port than "loads".

I think it's a misconfiguration.

Most probably it's just that you missed to set  CONFIG_LOADS_ECHO  in
the board configuration file and/or loads_echo in the environment.


The "timed out looking for echo" message is pretty clear to me  -  if
no  echo  is found, then there probably is no echo because it was not
turned on.

yes, I have set CONFIG_LOADS_ECHO in the configuration file. But the "loads_echo" 

does not show up in the environment. So I set it with the setenv command and now 

it's working fine. Maybe I have to check in the source code if the CONFIG_LOADS_ECHO
has any influence to the environment.

It affects only the _default_ environment, i. e. if you don;t have an
embedded environment in flash which gets overwritten when  storing  a
new image, and if there is already a valid environment in place, then
it will not take effect if you change this later.

I'm glad that I was able to help.

Now I got it. As long as u-boot finds a valid environment in the flash 
memory it will take that. If I change CONFIG_LOADS_ECHO in the config 
files, it affects only the default environment. After deleting the valid 
environment in the flash memory, the loads_echo variable shows up :-)

Thomas

Hi Thomas,

nice to see it works. Can you post a patch for the DK1S10 configuration that 
includes the corresct setup for loads command (CONFIG_LOADS_ECHO) ?


Thanks,
Stephan

I have a theory that it's impossible to prove anything, but  I  can't
