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.

Randal said it would be tough to do in sed. He didn't say  he  didn't
understand  sed.  Randal  understands sed quite well. Which is why he
uses Perl. :-)         - Larry Wall in <[email protected]>

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.

Thanks for your help.

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 :-)

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
prove it.
