now i am debugging an imx536 board which is made by ourselves,the USB can be recognized by the PC and
the MfgTools,but we can't use the MfgTool download image to microSD,and now when i power it on,it can't boot up,
when i send 0x05 0x05 to the board using serial terminal,it responses 0xF0 0xF0 0xF0 0xF0,then i press the reset key,
and send 0x05 0x05 to the board using serial termianl,it responses 0x33 0x33 0x33 0x33,but i don't know the meaning
of these information like oxF0 and ox33,i want to know if i can find the reason that the board can't boot up by using the
serial return information.
