Problem of hardware reboot

Hi,

 

   I have a trouble that I don't understand and I'll need some idea. I have made an embedded system with an IMX6Q powered by onboard regulators. It worked well but for some experience, I need to powered the IMX6Q with an external power, so I bypass onboard regulators. But now, the IMX6Q boot and during the initialization of kernel (after eudev is launched but it may be not linked), the IMX6Q reboot automatically, like if the board is power off and power on again.

 

   I supposed that I missed something when I bypass onboard power but I don't know what could happen. Which pins may create a problem like that ? I have checked that the power never fall and the pin RESET_MICO# is not the source of the reset.

 

Greetings,
