Jetson io tool: Fatal error

Hello, I have just installed the operating system for a Jetson Nano, and I wanted to configure the header by using the IO tool ( When I wanted to configure the header for the MCP2515 CAN Controller, there is an issue which you can see in the picture below.

The JetPack version used during the flashing procedure by SDcard method is 4.6 and the L4T version is R32.6.1

I would appreciate any help with this issue.

hello hernan.morales593,

it looks you’re having incorrect pin assignment there.
could you please share the configurations you had done.

Hello Jerry,

Well, this is the first configuration for the 40-pin header. I just executed the and selected option for the MCP2515 CAN. Then, I found this issue. As I mentioned before I have just installed the OS for the nano


Well, it looks like this version have some issues with the CAN dtbo. I have flashed the jetson several times with it, but in all of them I had the same problem. So, I have decided to use the JetPack version 4.5.1 where there is no problem with CAN.
