Orin Nano 4gb Can error

Hello !
I’m currently configuring an Nvidia Jetson Orin nano 4gb with aetina board (AIB-SO21) and I’ve got a problem when I want to configuring CAN module (Controller Area Network (CAN) — Jetson Linux Developer Guide documentation).
When I type the command “modprobe can” i got the error ““modprobe: ERROR: could not insert ‘can’: Exec format error””
And when I try " insmod /lib/modules/5.x.xxx-tegra/kernel/net/can/can.ko" i’ve got :
insmod: ERROR: could not insert module /lib/modules/5.10.104-tegra/kernel/net/can/can.ko: Invalid module format

Before I run insmod command i check if the file can.ko exist in the folder

If I try “cat /proc/device-tree/mttcan@c310000/status” the reponse is “okay”, and when I try “sudo dmesg | grep mttcan” i’ve got :

[ 4.169307] mttcan c310000.mttcan: Missing controller reset
[ 4.175075] mttcan c310000.mttcan: probe failed
[ 6.935731] net can0: mttcan device registered (regs=(ptrval), irq=111)

Have you ever had this problem with your card? Or is it due to the bsp aetina?

Sincerely,
Albouy Yann

Hi yannalbouy,

What’s your Jetpack version in use?

Could you run the following command on your board?

$ sudo modprobe mttcan

Please share the full dmesg and device tree for further check.
