[ts-7000] Where did I go wrong?

[wannabeanembeddedexpert wannabeanembeddedexpert <>]

Hi to all!!!

Finally I got a TS7200 about a month ago. Since I am not a linux guy :(:(  I decided to make some tests with cross-tools in

windows environment. So I have installed ARM Developer Suit; wrote my code - simply supposed to turn off leds. I have built

the source code below:

 

int main()
{
 unsigned int maskedVar;
 unsigned int *vAdrs = (unsigned int *)0x80840020; // leds
 maskedVar = (*vAdrs) & 0xFFFFFFFC; // last byte 1100
  
 *vAdrs = maskedVar;

 return 0;
}

 

I have ended up with ledProj.axf. Processor was configured as ARM920T. I have downloaded this image using RedBoot command

prompt with:

 

RedBoot> load -r -b 0x00300000 -h 192.168.1.13 ledProj.axf
Using default protocol (TFTP)
Raw file loaded 0x00300000-0x00302c0f, assumed entry at 0x00300000

 

And when I execute with "RedBoot> go 0x00300000" I end up with:

 

$T050f:e8033000;0d:88840000;#2c

 

at the hyperterminal. And no action with the leds. :(

Then I downloaded the linux image on the ftp of embeddedarm. And I have successfully loaded and ran this. So I assumed no

tftp error. I got suspicious with the file I have built and when I examine its Hex-view I saw first 4 bytes (file header,

right?):

 

"7F454C46...." which is equal to ".ELF....." in ASCII.

ELF? Must not it be AXF or something else? The header of the image on the ftp seems totally different by the way. In summary,

I could not find where I did wrong... Can anybody?
