Hi
 
I am now using the shamcom program to communicate with the SRV. I am already able to put my C-program into the flashbuffer,
and the 'zw' command seems to write the program to a flash sector. However, when I press 'Q' then, the program seems to crash
(I can't do nothing for over 2 minutes, and the C-test.c program isn't that heavy. the terminal won't accept any input)
 
What am I doing wrong? If you have a suggestion, it would really help my team a lot.

P.S should it matter, my OS is windows XP

I used the zd command, which returned the C-code, followed by some squares.
I included the printf("checkpoints"), but I am pretty sure the C-code is okay (it is one of your demos, c-test.c)
 
P.S Does the Q command executes a c-program stored in a flash sector or in the flash buffer? I thaught it executed a c-program in
a flash sector, but http://www.surveyor.com/blackfin/SRV_protocol_bf.html says otherwise...
 
Thnx

Okay
 
So now I put my C-program (code: see below) into the flash buffer using 'X' and checked with 'zd' that the program was successfully
uploaded to the buffer (which seemed to be the case).
However, 'Q' still resulted in my connection crashing.
 
this is the code of my program, main.c, which should resolve in the robot spinning around its axis.
 
int main()
{
motors(50, -50);
return 0;
}

Right
 
I removed the "int" from my program, so now I have that simple 5-line program you suggested.
However, Q still does nothing.
 
I thaught maybe the blackfin firmware was out-of-date, so I uploaded a recent version of it (10 march 2008).
This did not seem to solve the problem...
 
 
P.S After I press Q, the robot is completely jammed, so I have to power it off. My guess is that the blackfin tries to run the C-program, but gets stuck doing so...?

hm, now I get a "function undefined" message. (and no input can be interpreted afterwards).

I uploaded C-test.c, which seemed to be no problem. When reading out the flash-buffer content, I saw the program C-test.c,
followed by 10 arrows to the right.
 
Again, execution resulted in a crash.
 
I also tried writing the program directly via the 'E' command. (first 'zc' to clear the buffer, then 'E', 'I' and then:
main(){
print("hello");
exit(0);
}
 
after the last brace, I hit "enter", then "esc", then "X").
'zd' printed the program to the screen, this time without the arrows on the bottom.
However, the robot still crashed after hitting 'Q' .
 
P.S I also tried the program without the exit(0); line, but that didn't seem to matter much...
     when I put a "motors(0,50);" line in the program, I get a "unknown function" before the robot crashes, so I guess my  
     robot does try to read the C-program...

We only have one SRV, since we are given a limited budget
The firmware is  ##Version - TVM SRV-1 Blackfin w/C interpreter - 11:02:07 - Mar 10 2008
 

First send the 'V' command to confirm that you have a good connection.  You should see something like this -
 
##Version - SRV-1 Blackfin - 09:54:22 - Oct 10 2008 (stereo slave)
 
 
Then send the 'E' command to enter the line editor
 
E
(T)op (B)ottom (P)revious line (N)ext line (L)ist  
(I)nsert until ESC (D)elete line (H)elp (X)exit  
 
*  
*  
 
Then enter a simple program  -   send ESC to exit the Insert mode
 
* i
 
main()
{
print("hello");
}
 
*  
*  t             (points to top of buffer)
*  l             (lists the first 20 lines)
 
main()
{
print("hello");
}
 
* x    
leaving editor  
 
 
Then send the 'zd' command to display the contents of the flash buffer which holds the program
 
zd
##zdump:  
 
main()
{
print("hello");
}
 
 
Then send the 'Q' command to execute
