How to use the WDOG1 signal of i.MX6Solo

[yuuki]

Dear All,

In our system, the external device is reset by using WDOG1 signal of i.MX6Solo.

When WDOG time-out occurred, we want to reset an external device by making GPIO_19 to Low by software.

Does such a usage have any problem?

If no problem,
Would you advise it about the setting method?

Or should WDOG1_B signal be used?
(from DISP0_DAT8 pad or GPIIO_9 pad or SD1_DATA2 pad)

May I have advice?

Best Regards,
Yuuki

Hi yuuki

one can use wdog interrupt and toggle GPIO_19 by software

in wdog interupt routine, this is described in sect.70.4.8 Interrupt IMX6DQRM

WDOG1_B resets processor, so I would not recommend to use it for such

task.

Best regards

igor
