board freeze after indeterminate duration

[wolfgangschneid]

we have a custom i.mx6d board with android 5.0.2 implementation. after indeterminate duration the board freezes without any debug information on the serial console. we have done RAM calibration with the stress test tool and several memory tests without any error. mtest in bootloader and memtester in kernel with overclocking (580Mhz) an high temperature without error.

Hello Wolfgang,

    if you want to display booting logs on serical console, you should modify booting parameters of u-boot, add "selinux=disable" to environment of u-boot, then save it and reboot.

Hello Weidong,

we have already done this. see the copy from the console.

        enable_wait_mode=off console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=400M androidboot.selinux=disabled androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M vt.global_cursor_default=0 enable_wait_mode=off

we can't search for a mistake because the system tells us nothing !

do you have another idea ?

Hello Wolfgang,

      Can android successfully boot? For example, android GUI is normally displayed on screen.
