Hi, Kim,Kwansuk! It seams you have the same problem that I had just two weeks ago. It is likely you have the serial port located below 0xc0000000. If it is so, I suggest you to move the serial port above 0xc0000000. If you want to know the reason, just find the mails, in this mailing list, titled "Re: execve system call question"
