Re: [ECOS] Redboot load problem

["Michael Anburaj" <embeddedeng at hotmail dot com>]

Hi Swaroop/Dhiraj,

I have text files explaining the issues connected to this (for both 
downloading SREC & BIN) at my site. I will extend it for elf files sooner.

The start address used for ?go? need not be same as the load address. So, 
you are better of loading a SREC, which would contain both these addresses 
in it (so, need not explicitly specify). I would imagine the same for elf?s 
too.

Cheers,
-Mike.
