PROCESSOR-SDK-AM335X: Build .ko file for at24.c driver

Niraj Kumar

Hii,

I want to build .ko file for at24.c driver to access eeprom memroy chip. I am trying to build but not happening from SDK v04.

And now I forgot where I put at24.o file to generate .ko file.

And In SDK v08, Previously I did .ko file but I am trying to load to access eeprom memory chip but it is not happening.

I have attached what I am getting when I am trying to load at24.ko file.I hav built through SDK v08.

root@am335x-evm:/home# insmod at24.ko
[ 9571.128720] at24: disagrees about version of symbol module_layout
insmod: ERROR: could not insert module at24.ko: Invalid module format

Regards

Hello Niraj,

PLEASE stop creating a new thread every day around the same subject. This is still a generic Linux question, not a question about TI software. We are not StackExchange, StackOverflow, etc. Please look for help with generic Linux questions somewhere else online.

If you build a module for one kernel version, and then try to load it with a different kernel version, you will run into errors.

The TI documentation for using the TI makefile to build kernel modules is here: https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/08_02_00_24/exports/docs/linux/Foundational_Components_Kernel_Users_Guide.html#compiling-the-kernel-modules

Nick
