Hi Gary,

Thanks for the info.

My time measurements on Window Hyperterminal:
It printed "CCCCCCCCC\x15\x15", 11 characters in 30 seconds. So, it has 3 seconds 
inter-character gap approximatly. Which I think is pretty ok from what you 
said in the eariler email.

Are you developing on Windows?? If so, what terminal program are you running 
this on? Let me know what you think about this.

Thanks a lot,
-Mike.

Hyperterminal screen capture:
RedBoot> load -m xm
CCCCCCCCC\x15\x15\x15\x15\x15\x15\x15\x15\x15\x15\x15Can't load '': Timed out

Hi Gary,

I found the problem,

The RO_base (Or the Location the ecos application to be loaded in RAM) is 
pointing to a ROM address.

1st 2 lines from the generated Srec:
S010000077616C6C636C7E312E73726563E6
S3159FC000000500001000000000000000000000000076

The address 0x9FC00000 is in the FLASH (Reset vector address).

I guess, I have linked the application for FLASH. How do I link it for RAM? 
And also let me know a method to alter the RO_base (Program space) & RW_base 
(Data space) address without using the Memory Layout Window (becaue this is 
not supported in Conf. Tool 2.08).

Thanks a lot,
-Mike.

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.
