on Jetpack 4.6

I am trying to configure the pins to use the spi1 to connect an OLED screen to my Jetson nano. When I try to run, a grey screen flashes and takes me back to the terminal. The error I get is:
Multiple DTBs found for NVIDIA Jetson Nano Developer Kit!
Although I have one file in /boot/dtb/ named: kernel_tegra210-p3448-0000-p3449-0000-b00.dtb

Any idea how to solve this issue?

I am facing the same exact problem, and I have been searching for solutions for days and nothing worked.

Do you mean you observe the issue while executing on default image? Or after you have generated the dtb through, reboot the device and then hit the issue?

Hello, I am facing the same issue.
I first run on the default image with Jetpack 4.6, enabling PWM and SPI.
I have rebooted the device and then hit the issue.

I managed to solve this thanks to the solution in Jetson-io bug

c = get_compatible(dtbo).split() → c = get_compatible(dtbo)
for c_str in c: → for c_str in c.split():

Hope it helps !

hello dodo.ibt,

thanks for sharing,
the changes to fix an error when get_compatible(dtbo) returns None has already check-in to rel-32 code-line,
since the latest L4T release is r32.7.1, you may moving to the latest release for confirmation.
