Palliser, thanks very much for your help !
I erased and reset your my board and I relaunch my commad line.
The messages displayed are :
Erase flash
Write 9748 bytes to flash
[==============================] 100% (39/39 pages)
Verify 9748 bytes of flash
[==============================] 100% (39/39 pages)
Verify successful
Set boot flash true
CPU reset.
The program uploaded is running correctly ! Yes !
But if I try to relaunch my command line, It doesn't work !!!
I must erase and reset my board before upload my program...
But, I don't understand why the message displayed is different of Arduino IDE:
Erase flash
Write 9748 bytes to flash
[ ] 0% (0/39 pages)
[======= ] 25% (10/39 pages)
[=============== ] 51% (20/39 pages)
[======================= ] 76% (30/39 pages)

And why I must erase and reset my board each time I want to upload a program ?
Thanks.
Nassa.
