It was hangs after network started like this link http://buildroot.uclibc.org/downloads/manual/manual.html#faq-boot-hang-after-starting.

Or any way to use buildroot for this board.

    Hi,

    I believe the answer to your problem is inside the link you posted:

    In order to have the system start a shell on your serial console, you have to go into the Buildroot configuration, System configuration, and modify Port to run a getty (login prompt) on and Baudrate to use as appropriate. This will automatically tune the /etc/inittab file of the generated system so that a shell starts on the correct serial port.

    Best regards,
    Miroslav

    Hi,

    Which kernel version are you using? Are you using the officially supported TI AM335x SDK/PSP? Which SDK/PSP version?

    Please post your .config file (located in the main kernel source code folder), your /etc/inittab (located in your root file system), and finally print your U-Boot bootargs (while in U-Boot mode use this command: print) and post them here.

    Best regards,
    Miroslav

    Hi

          Thank you for your kindly.At the first time I use u-boot,kernel (linux-3.2.0,psp05.06.00.00 ) and Arago's file system that provided by TI.

    It's works correctly.But that file system not have utilities which I want to use such as ftpserver,nano editor.

    So I use buildroot to building file system and then have that problem.

         configuration and other files I'll attach tomorrow.

    Best Regards
