kexec support

I want to use kexec in my system to boot to new kernel while the parent kernel is still running.

(kernel ver 2.6.37). While attempting this , the new kernel  boot process is halted in the middle and is stuck forever.

Is any one successfully used kexec on any of TI platforms?

    Hi JK,

    I have personally did not try kexec feature, but I see that some community members are using kexec:

    http://e2e.ti.com/support/embedded/linux/f/354/t/284335.aspx

    http://e2e.ti.com/support/embedded/android/f/509/p/155364/588379.aspx#588379

    You should also enable kexec in the linun kernel .config file:

    #
    # Boot options
    #
    CONFIG_ZBOOT_ROM_TEXT=0
    CONFIG_ZBOOT_ROM_BSS=0
    CONFIG_CMDLINE=""
    # CONFIG_XIP_KERNEL is not set
    CONFIG_KEXEC=y
    CONFIG_AUTO_ZRELADDR=y
