Hi, thank you for your response.
1. No that's the command line that I have tried to use (the one which unbrick the board) but the programming stucks where I mentioned.
2. Yes, that page helped in this issue, I just use this command line:
./uflash -d /dev/mmcblk0 -u my_program.ais -p OMAPL138 -e 0x80000010 -l 0x80000010
Now the program runs from the shared ram and booting from the sd.
