Part Number: AM3352

Tool/software: Linux

Hi All,

we made a customized board with AM3352 processor, 1GB DDR3 and 512 MB Nand flash. we are using am335x-evm-linux-rt-sdk-src-04.00.00.04.tar.xz and arago-base-tisdk-image-beagleboard.ubi. we compiled and flashed the Linux, filesystem and DTB in NAND Flash.

When we give run nandboot, the following issue occur.

Starting kernel ...

and hangs,

What can be the issue. Where the modification has to be done ?

Regards,
Avinash N

    Hi Avinash,

    The above console output is printed by the u-boot boot-loader when starting linux and the message "Starting kernel..." is last message that u-boot will print before starting the kernel. The above problem is typically caused by mis-configuring the tty interface that the linux kernel uses by default for displaying the console messages. The default tty interface used the linux kernel for Sitara devices is configured in the kernel menuconfig or also you can check the tty interface being used for an Sitara device by viewing the kernel .config file and seeing CONFIG_CMDLINE option value.
    For example:
    CONFIG_CMDLINE="root=/dev/mmcblk0p2 rootwait console=ttyO2,115200"
    or boot environment variables 'console=ttyO2,115200n8'

    Hi,

    We have made the changes as per the above recommendation. But still we are facing the same issue.

    => run nandboot
    Booting from nand ...

    NAND read: device 0 offset 0x80000, size 0x40000
    262144 bytes read: OK

    NAND read: device 0 offset 0x200000, size 0x800000
    8388608 bytes read: OK
    ## Flattened Device Tree blob at 88000000
    Booting using the fdt blob at 0x88000000
    Loading Device Tree to 8fff2000, end 8ffff75d ... OK

    Starting kernel ...

    What can be the issue? Can any one support ? It has become a serious issue?

    Regards,
