Dear all,

        As I posted  in the discussion

WiFi&BT Related kernel panic in mx53 SMD tablet

the issue causes those kind of problems and It has not booting even when I have just press the Hard reset button or when I just give the command

adb reboot-bootloader in the ADB console.

  In serial down-loader mode also it cannot able to detect by Host.

by these things and as I mentioned previously in

WiFi&BT Related kernel panic in mx53 SMD tablet

the problem  was left by removing Wifi and Bt module, but while autooboot  stop has not worked and while I am opening camera ,It gave error and the serial console at that time is

Unhandled fault: external abort on non-linefetch (0x1018) at 0x4155a054

Hello, Muthe:

From above descriptions, do you have chance to check relative power supplies are still normal in your board?

For such kind of logs, it's normal if the use cases use FSL audio codec:

Unhandled fault: external abort on non-linefetch (0x1018) at 0x4155a054

hello Xiaoli Zhang,

    Thanks for you support ,

          The boot ROM code has to intialize the UART And in Serial Download mode it has to communicate with Host.

These two cases have failed , Is that due to damage of any Hardware or processor,

thanks&regards,

Muthe.

Hello, Muthe:

I am not sure. Do you have asked any Hardware guy to check your board? We didn't meet such kind of problems in our side. If no HWguy helps to check your board yet, i will check with our HW engineer and see whether he can give some advices.
