hi,
First of all thanx to Jonathan Larmour for ur response.

I am downloading RED BOOT.
What is ROMRAM Stratup. I tried to search the net. But found 
nothing. From where can I get to know more abt it


And Any Ideas on Changing ROMC0N0 not working on BSL.
Wll it work on RedBoot. This was my second question that day

ROMRAM startup is an eCos option, which loads the eCos code from ROM into RAM 
and executes there. Executing in RAM is usually much faster than in slow 
EPROM.

Anyhow, You can find the latest eCos and RedBoot docs WITH SEARCH at

ROMRAM startup is where the program initially starts in ROM and pretty
much straight away copies itself to RAM and runs from there. Other ARM
HALs support it, just not the E7T yet. To add it, at a minimum you need to 
add a new memory startup type, different from ROM or RAM.

The best way to find out about it is to look at other HALs. The ebsa285, 
edb7xxx, at91 and integrator HALs all support it. Search those for 
"ROMRAM" and look at their ROMRAM memory layouts (in the include/pkgconf 
subdirectories of their packages).

Once you see what's required for them, you would then know what to add to 
the E7T HAL.

I have no idea, sorry. I don't know anything about BSL.
