[ECOS] Redboot: "load -m xmodem" command

[ECOS] Redboot: "load -m xmodem" command

[Mike A]

Hi,

I Redbooted my ATLAS(MIPS 4Kc) board. Then at the console prompt "Redboot>" 
(on Windows Hypertermial) I typed in the command to load the RAM image "load 
-m xmodem". Then I select Transfer->Send file (on Hyperterminal). with the 
following options I then click OK,

Protocol: Xmodem
file: 
C:\myrep\examples\t\t_install\tests\io\wallclock\current\tests\wallclock.srec

The file does not get download...

Even before I start sending from the PC, I see a lot of 'C' being sent from 
Redboot in response to "load -m xmodem"

I even tried with ymodem.. I wasn't sucessful

Any clue??

Thanks alot,
-Mike.

The most probable cause is that HAL_DELAY_US() isn't working properly.
The way to check is run the same command (load -m xm) and don't try to
start the transfer.  You should see a string of "C" characters, but they
should only come out at a rate of one every 3 or 4 seconds.  Any faster
says that the HAL_DELAY_US() macro is broken.

If this is the case, try and fix it and rebuild RedBoot.

As always, if you make changes, it would be nice to pass them back to 
the project.

Sorry:

 I've been off for a few days. In fact, I never used RedBoot xmodem or zmodem. 
I usualy work with GDB or Insight to load, debug and run eCos programs. For 
loading only  I used only transfer from the tftp server on ethernet.

 Maybe somebody else can tell You how it works.
