I’m trying to use the SPI1 bus on a Jetson NANO configured using Jetpack 4.3.
I followed the instruction from https://www.jetsonhacks.com/2020/05/04/spi-on-jetson-using-jetson-io/ to enable the SPI1. I want to use the SPI to send some info from live detection from jetson-inference ./detectnet csi://0.
The problem before setting the 40-pin configurations the fps was 24-25 … after setting it up, the fps dropped to 3-4
when using simple_camera.py from CSI-Camera repo it lags and it’s really affected.
I know that the problem from the configurations because once I did it I tested it because I reset my nano because of it.
The SPI shouldn’t affect the camera frame rate.
Did you check with below command to check the fps?
gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM),width=1920,height=1080,format=NV12' ! nvvidconv ! fpsdisplaysink video-sink=fakesink --verbose
I updated to Jetpack 4.6
Yeah I checked that and from CSI-Camera repo I checked the simple camera etc… I guess there was a compatibility program. Because my Nano became much slower after configuration. So you can close the thread.
