once again thank you gtj0 and chrishamm, couldnt have done it without you.

@chrishamm thanks Chris, sorry if that should have been obvious, Im still very new. which also makes me feel anxious having to ask this now. so after enabling duet web server and running "sudo systemctl status duetwebserver" I get the following. my question is why is it showing "inactive". thanks again for your help.

mr_solderem@Duet3:~$ sudo systemctl status duetwebserver
● duetwebserver.service - Duet Web Server
   Loaded: loaded (/usr/lib/systemd/system/duetwebserver.service; enabled; vendor preset: enabl
   Active: inactive (dead)

@gtj0 so running duet control server with debug returns

mr_solderem@Duet3:~$ sudo /opt/dsf/bin/DuetControlServer -l debug

running sudo systemctl status duetwebserver returns

mr_solderem@Duet3:~$ sudo systemctl status duetwebserver
● duetwebserver.service - Duet Web Server

I noticed i was getting an error about my host name not matching the M550 assigned name so i changed it to "Duet 3" and that seemed to fix that, though I'm still not sure why duet web server still is not active. Any thoughts?

@gtj0 thanks for the reply, this is the output from running "ls -al /dev/spidev*"

mr_solderem@Mr:~$ ls -al /dev/spidev*
crw-rw---- 1 root gpio 153, 0 Jun 19 15:59 /dev/spidev0.0
crw-rw---- 1 root gpio 153, 1 Jun 19 15:59 /dev/spidev0.1
crw-rw---- 1 root gpio 153, 2 Jun 19 15:59 /dev/spidev1.0
crw-rw---- 1 root gpio 153, 3 Jun 19 15:59 /dev/spidev1.1

so you were right, I forgot to change the data transfer ready pin to pin 13. Now i have a connection over SPI.

though it seems like it is hanging, I'm heading out the door now, so ill have to see whats causing the hang up tomorrow, but this is a huge step forward. thank you again for the help.

@gtj0 I hate to reply to such an old thread but this is the only one i could find that described the set up of the jetson nano as a SBC with the duet 3. My issue is I am following the steps that Hans nicely wrote out in his post here https://forum.duet3d.com/post/212946 . however when i add the single-spidev.dtbo file to /boot/ I cannot get this option to show up in jetson-IO under "configure for compatible hardware". I've also tried manually adding the .DTB file to /boot/ and having the extlinux.conf file point to that .dtb file, but when i run duet control server i still get the waiting for transfer ready timeout error. I've tried both a a02 board as well as a b00 board. any insight would be greatly appreciated, thanks for all the info providing in this thread its been a huge help.
