Hi NVIDIA,
pinmux是否能配置SPI IO输出3.3V？例如，在pinmux的excel表格把SPI1的3.3V Tolerance Enable设置为enbale，是否能让它输出3.3V？
Hi 751244340,
Are you using the devkit or custom board for AGX Orin?
What’s the Jetpack version in use?
It seems there’s a level shifter on the devkit board to output 3.3V for SPI related pins.
我们使用custom board，Jetpack6.0.
我们硬件需要加1个电平转换芯片把1.8V转3.3V是吧？
Correct! You can refer to the design guide for carrier board.
It is 1.8V from SoM and there’s a level shift on the devkit board to transform it to 3.3V.
KevinFFF, thank you so much!
