[U-Boot-Users] srec download fail
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

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.

Did you configure "cu" as documented in the DULG?

Is "loads_echo" set to 1 in your environment?
It does not work with kermit either. The loadb cmd with kermit works fine.
S-Record download with kermit is not supposed to work.

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
