How to enable CAN ISOTP in Jetson nano orin L4T R35_v3.1

[Orin_master]

Hello,

I am using CAN protocol in the jetson nano orin dev board using this wik. Now I am planning to enable can-isotp in the L4T. For can-isotp to work the kernel requires can-isotp.ko to be installed and also from kernel version 5.10 the CAN transport protocol should be enabled by default.

The R35_v3.1 doesnt have can-iso tp.ko module and I want to know how do we enable this in the latest l4T for jetson orin nano dev board.

Best regards,
Orin user

Hi Orin_master,

From Makefile, it seems CONFIG_CAN_ISOTP decides if it should be enabled.

obj-$(CONFIG_CAN_ISOTP)	+= can-isotp.o

Have you tried to enable CONFIG_CAN_ISOTP in kernel defconfig?

Hello KevinFFF,

No, I have not tried this with rebuilding the kernel with CONFIG_CAN_ISOTP flags enabled. I will try it. Thank you.

Between do you have any plan to include this with the future L4T kernel image along with the other CAN modules(CAN, CAN_RAW, MTTCAN).

Please help to try enabling that kernel config.
Sorry, we don’t have plan to enable that by default.
It seems not necessary for Tegra CAN.
