Re: The voltage of SYSBOOT2 is 1.47V

Hi Dave,

    Actually,my problem is system hangs on x-loader. The board can
boot from SD card at first time(loading Linux kernel and run ....),but
fail in next coming boots.If I let the board place over a night,the
board can boot up again. However,the problem is the same,"can boot at
the first time,but fail in next coming boots".

regards,

Sean
