A603 and spi

I have gotten my orin nano flashed and booting using the a603 carrier board I purchased from seeedstudio. They do not have a dtb file for this board as of yet and wanted to get the serial working on the board. Out of the box loading the spidev module gives me spidev0 spidev1. I assume that is for the devkit. What is the best way to go about getting spi going on this carrier board. I am still waiting on seeedstudio to reply to my inquiry about the dtb

I got a loopback test after using the jetsion-io to configure the pins.

root@ubuntu:~/spidev-test# ./spidev_test /dev/spidev0.0 -v
spi mode: 0x0
bits per word: 8
max speed: 500000 Hz (500 KHz)

RX | FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF F0 0D | …@…�…�.

next thing is to see if I can get the gy-91 detected properly
