iMX6Q : How to use the /WDOG1 signal before the uboot is booting

[koichisakagami]

Dear community,
We have been developing our product with iMX6Q.

In figure 8-2 USB Boot Flow of IMX6DQRM Rev. 3,
it said ARM core will reset if no any activity within 90 seconds when WDOG_ENABLE=1.

[Question]
    Then, is the /WDOG1 signal  outputed to iMX6 I/O pin ?
    (DISP0_DAT8 pad or GPIO_9 pad or SD1_DATA2 pad)

    I  want to use the /WDOG1 signal for being detected external device .

Best Regards,
    Koichi Sakagami

Hello,

   Software (internal) reset is produced by the  internal serial  boot ROM.

Have a great day,
Yuri
