I would like to "thank you" everyone who did answered to my questions.
I got now a simple code to work, my first stand alone application :-) - I did
used that values suggested by Wolfgang Den and Alessandro Rubini, both values
work :-)
I did read the include/configs/sam9l9260.h but I couldn't understand where is
the information of the first address on SDRAM that I can use for a standalone
application. I am not worried for now about that.
I tried a more complex code that uses a periodic interval timer to do a delay
on flash LED code however this code does not work, It comes back to U-Boot
shell with return value of 1. What can I be doing wrong?
So, to resume and maybe in hope to help someone like me:
My standalone application that is working:
http://code.google.com/p/rockboxplayer/source/browse/flash_led-0.c
My make file:
http://code.google.com/p/rockboxplayer/source/browse/Makefile?r=11
And I just needed to do on U-Boot shell:
"tftp 0x20040000 flash_LED.bin" and after "go 0x20040000" :-) :-)
Thank you all :-) :-)
