I have an adaptor that has a TI TCAN4550 CAN controller that interfaces to the Nano using SPI.
The upper layer will be J1939.
There are sources for both of the above in the Linux source tree on GitHub, but not in the public sources for the Nano.
I have attempted to build the kernel with the added sources.
I am able to configure them with menuconfig, but they don’t appear in the output.
I may have not got the makefiles correctly setup.
I’m new to this and I’m stuck.
Any help would be appreciated,
