Tool/software: Linux
I am running sdk: ti/sdk-linux-am57xx-evm-03.00.00.04
I executed the following steps, but still get "[ 8.633798] cmemk: disagrees about version of symbol module_layout" during linux boot.
1) First I modified the .config file for my build and rebuilt my bootable linux image: zImage in the /home/tantles/ti/sdk-linux-am57xx-evm-03.00.00.04/board-support/linux-4.4.12+gitAUTOINC+3639bea54a-g3639bea54a.
2) Next I rebuilt all modules to match this zImage by building: make modules
3) Finally I installed all the newly rebuilt modules using: sudo make ARCH=arm INSTALL_MOD_PATH=/srv/rootfs modules_install
4) Then I rebuilt cmem.ko as follows so that it would match the zImage too (I modified the Rules.make file so that it would NOT rebuild linux for me, but simply rebuild the cmem module):
$ make cmem-mod_no_linux

Despite all these steps, I still get this error on linux boot: cmemk: disagrees about version of symbol module_layout
Any Idea what is going on?
