[ECOS] Trouble with loading an exe on Redboot (XScale DBPXA250 platform)

[ECOS] Trouble with loading an exe on Redboot (XScale DBPXA250 platform)

[Pascal Pediroda @ Brime]

Hello,

When trying to download the eCos image inside the target, (load -m ymodem)
after 30 seconds, it fails:
message CCCCCCC.......... Can't load Time out

I sow in an old thread of the list such an issue but the solution was to use
the -c 0 option.
This option is not understand by my redboot version.

Anyone has already experienced this ?

Thank you.
Pascal

As soon as these messages start coming out, you need to tell
your communication software (minicom, HyperTerm, ??) to send
the file using X-modem.  RedBoot can't make that happen automatically.

I don't know where you found this - ignore it.

[ECOS] R: [ECOS] Trouble with loading an exe on Redboot (XScale DBPXA250platform)

[Pascal Pediroda @ Brime]

Hello,
I use minicom .
After executing the load command from it, I press CTRL A , S select Ymodem ,
select my image to download and then enter.
Do you mean that it does not begin the load ?
I thought that the dots were meaning that sth has been downloaded !
I have to check if it works the same with Xmodem.
Thank you

minicom should pop up a little window showing that it's trying to 
communicate with redboot. If it isn't doing that you probably aren't using 
minicom quite right. Have you selected the file with space?

Also make sure you don't take too long over it otherwise redboot will time 
out waiting!

[ECOS] R: [ECOS] R: [ECOS] Trouble with loading an exe on Redboot (XScale DBPXA250platform)

[Pascal Pediroda @ Brime]

In the little window that pops up I have :
Ymodem sector/kbytes sent: 0/ 0k Retry 0: NACK on sector
Rewtry 0: NACK on sector
Ymodem sector/kbytes sent: 3/ 0k Retry 0: Got 24 for sector
ACK
Retry 0: Got 24 for sector ACK
Retry 0: Got 24 for sector ACK
Retry 0: Got 24 for sector ACK
...
...

Does it seems to work correctly to you ?
Thank you

Yes. Sometimes it has to retry a few times at the outset to get into sync, 
but then gets going. Definitely try and select the file quite quickly from 
the outset to give it more time to sync.

I would ask you to check that you're using a recent redboot, but I know 
you can't be if it's the DBPXA250 as that's a port Intel refuses to 
contribute, so it won't have many fixes. Hassle them about it. In the 
meantime you could try to merge in any fixes yourself from the public code 
base. Have a look at redboot's xyzmodem.c. I know intel have heavily 
customised their redboot package in general so you can't necessarily just 
substitute in the current redboot package.

You could also try xmodem instead of ymodem - if it fixes the problem, who 
cares.

Of course one possibility is that the serial can't keep up and you're 
dropping characters - you could try a lower baud rate, either with the 
baudrate command or you may have to recompile your redboot.

Or there may be some other problem causing character loss such as flaky 
hardware.

Isn't this ASCII for "$"?  After this happens (and the minicom download
gives up), do you get the RedBoot prompt back?

[ECOS] R: R: [ECOS] R: [ECOS] Trouble with loading an exe on Redboot (XScale DBPXA250platform)

[Pascal Pediroda @ Brime]

Hello Jonathan, hello Gary,
When I have the popup window of ymodem on the host side, I have redboot
hanging.
After a while, ymodem says that the transfer is incomplete.
BUT, I have resolved the problem : it was linked to the avaialable RAM
memory.
On the RedBoot user's guide I have, it was written to use the command
"version" in
order to get the first free offset in RAM...
I have shifted this address from 0xa0000000 to 0xa0100000... and the
transfer was complete.

Now I am trying to do the same with tftp (I also have an Ethernet
connection) but the load command is immediately finished,
I don't think that it had enough time to transfer the file !
