I wrote the driver on Orin, but the kernel lacked the necessary modules for the driver. The module is not installed, nor is the function export table.
I loaded the missing module separately, but there is still no module function export table in the kernel. For example, if I write a program that uses printf, the system can’t find the implementation of this function.
how you compile the kernel module, did you have *.ko file generated?
please see-also developer guide, To Build External Kernel Modules for reference,
thanks
I’ve compiled *.ko file from the source code.
I have found this problem because I selected the wrong file to replace the missing library and header files. Cause my function can’t use normally.
