Hello,

In the i.MX 8M Mini hardware developer's guide, table 8, it suggest to pull GPIO1_IO02 (WDOG_B, ball AG13) high with a 100k ohm pull-up resistor. However, in section 5.5 of the same document, Note 2 says to pull the pin high with a 4.7k ohm resistor. Which value is actually recommended?

Thanks

Hi adevries 

100k ohm is sufficient, also one can use internal pull-up as described in

attached i.MX8M Mini EVK schematic p.12.
