How i need to enable and work wit SPI communication in the jetson nano?
Hi saravanank1423,
Are you using the devkit or custom board for Jetson Nano?
What’s your Jetpack version in use?
You can refer to Jetson Nano SPI Bus Not Working - #10 by KevinFFF to verify SPI loopback test first.
how to install the jetpack version.currently i am using devit.
For the devkit, you can refer to SDKM to flash your board.
how install jetpack in the terminal
Please refer to Preparing a Jetson Developer Kit for Use for details.
if i download the jetpack it showing error unable to correct problem,you have held broken package.
How do you download Jetpack?
It seems you have some environment issue if you see the message of “broken package”.
Are you working on an Ubuntu host PC?
right now i am working on it.whether the jetpack is needed for the SPI communication and which version jetpack we need to use.and which ubhunthu version we need to use in host PC.
No, I just want to know what’s the release you are using.
Please share the result of the following command on your board.
$ cat /etc/nv_tegra_release
For Jetson Nano (which should come with JP4), you can use Ubuntu 18.04 or 20.04 as your host PC for development.
i have flashed with jetpack what to do next.
Please refer to it step-by-step to verify SPI loopback test.
it is not working
i have enabled the SPI communication give me a program so that data transfer between two jetson nano via SPI Communication.
Do you finish every steps in my link?
Or you have issue at any step?
Do you mean that you are verifying SPI communication with 2 Jetson Nano devkits?
yes,I need to verify between two jetson devkit.There is no issue in the link you provided.
If you’ve verified SPI loopback test as the link I shared, it means the configuration on the devkit is correct.
Now, you just need to get two devkit and setup one as master and another as slave(by specifying compatible as nvidia,tegra210-spi-slave).
