5. script.bin.default
   

Copy code

Ok now I read sunxi-tools to undertand how to open it ....

1. Usage: ./sunxi-fexc [-vq] [-I <infmt>] [-O <outfmt>] [<input> [<output>]]
   
2. 
   
3. infmt:  fex, bin  (default:fex)
   
4. outfmt: fex, bin, uboot  (default:bin)

Copy code

xwalter

1. root@OrangePI:/media/boot# bin2fex script.bin > script.fex
   
2. bash: bin2fex: command not found
   

Copy code

xwalter

command not found but is there ....

1. 
   
2. cd /media/boot
   
3. ls
   

Copy code

1. bin2fex

ok guys
I follow this ....
sunxi-tools-master/bin2fex script.bin script.fex
Now I have my script.fex opened ....
What about uarts.....

1. [uart0]
   
2. uart_used = 1
   
3. uart_port = 0
   
4. uart_type = 2
   
5. uart_tx = port:PA04<2><1><default><default>
   
6. uart_rx = port:PA05<2><1><default><default>
   
7. 
   
8. [uart1]
   
9. uart_used = 0
   
10. uart_port = 1
    
11. uart_type = 2
    
12. uart_tx = port:PG06<2><1><default><default>
    
13. uart_rx = port:PG07<2><1><default><default>
    
14. uart_rts = port:PG08<2><1><default><default>
    
15. uart_cts = port:PG09<2><1><default><default>
    
16. 
    
17. [uart2]
    
18. uart_used = 1
    
19. uart_port = 2
    
20. uart_type = 4
    
21. uart_tx = port:PA00<2><1><default><default>
    
22. uart_rx = port:PA01<2><1><default><default>
    
23. uart_rts = port:PA02<2><1><default><default>
    
24. uart_cts = port:PA03<2><1><default><default>
    
25. 
    
26. [uart3]
    
27. uart_used = 1
    
28. uart_port = 3
    
29. uart_type = 2
    
30. uart_tx = port:PA13<3><1><default><default>
    
31. uart_rx = port:PA14<3><1><default><default>
    
32. uart_rts = port:PA15<3><1><default><default>
    
33. uart_cts = port:PA16<3><1><default><default>

Copy code

now ...?
[uart3]
uart_used=1  ---this is ok if I want to use it
uart_port=3   ...this ok  --> /dev/ttyS3
uart_type=2  ....this ok  I use only two pins , PA15 and PA16 don't exist
But not work ....

xwalter

ok guys now it seems work .
I have also tested a java application echo with netbeans in orange side and putty in win7
Very good !!!

xwalter

There is a problem ....
I start the java application which use the /dev/ttyS3
In win7 I start putty and connect over my windows serial port 5 at 115200
The java application under netbeans is running and waiting for something over serial uart3 .
When I send something from putty I receive the orange pi login and password
It seems that the /dev/ttyS3 is connected with a console but isnt' true because gtkterm hasn't any port connected and minicom is connected to /dev/ttyS0
And then ....this happens if I use putty but also a simple windows under visual studio .
Pratically the /dev/ttyS3 responds as if I want to connect with terminal ....very hard to solve that ...But if I close tightvncserver everithing run well .

WereCatf

You have agetty or similar running on ttyS3.

xwalter

you are right because two day ago I wrote

1. systemctl enable serial-getty@ttyS3.service

Copy code

And when I reboot or restart this remain permanent , maybe
I want to try to disable that ....by typing

1. systemctl disable serial-getty@ttyS3.service

Copy code

xwalter

Now is much more better .
I hope to solve in this way ....
