@tom got it, I think you indirectly answered my question by giving me the last valid configuration. Am I looking in the right place?:
voxl sdk 1.5.0 -> system image 1.8.04 -> recipes-kernel/linux-msm/files/dts/common/m0xxx-modalai-gpio.dtsi :
&soc { voxl_gpio { ... modalai,gpio-init-output-high = <0 1 53 56 57 85 86 87 88 89 124 152 157 159>; modalai,**gpio-init-output-low** = <36 37 **46** 54 55 67 82 83 84 131 153 154 155>; modalai,gpio-init-input = <48 49 50 51 52 110 111 112 113 114>; status = "ok"; }; ... };So settings for gpio pin 46 on sentinel w/ spektrum receiver should be direction:out, value:0 assuming they aren't overwritten somewhere else.
