I’m trying to test gpio output setting by default.
I applied pinmux output setting as follows :
- Pinmux Table
Generated file as follows:
And I build and flash DTB.
I checked output setting on Jetson NANO :
GPIO3_PB.06 => GPIO-14 => 0xe
GPIO3_PB.07 => GPIO-15 => 0xf
So, It looks my setting was applied.
But, there is no output signal by default.
I checked the extension header pin with a multimeter, there is no output voltage.
GPIO-14 => extension pin 13
GPIO-15 => extension pin 18
And kernel-gpio isn’t sat, also.
I wonder what i missed?
And how can i read current gpio status?
