imx6ull evk - i2c2 via arduino header

[jorge_ramirez]

hi,

I am trying to access i2c via the arduino header J1704.

Could you let me know what IOMUXC value should be applied to SNVS_TAMPER2 (as described in the RM  rev1 11/2017 page 1527) to guarantee the 3.3V supply on the pin?

thanks

Jorge

Hi Jorge

iomux settings (pinctrl_i2c2: i2c2grp) can be found on :

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm/boot/dts/imx6ul-14x14-evk.dtsi?h=...

Regarding voltage - SNVS_TAMPER2 pin is powered by VDD_SNVS_IN Power Group

as described in Table 91. 14 x 14 mm Functional Contact Assignments
