SDK v2.0-1703, Module kernel (Cache: QorIQ Linux SDK v2.0 PPCE6500 Yocto) error when I do an insmod MyModule.ko.

[iuro]

Hi everyone!

I am trying to update with SDK v2.0-1703 because, I am building a module kernel (currently with Cache: QorIQ Linux SDK v2.0 PPCE6500 Yocto) and I get a message error when I do an insmod MyModule.ko.

[ 2022.496533] MyModule: disagrees about version of symbol device_destroy
[ 2022.502025] MyModule: Unknown symbol device_destroy (err -22)
[ 2022.506759] MyModule: disagrees about version of symbol device_create
[ 2022.512157] MyModule: Unknown symbol device_create (err -22)

Also, I can not download from Git address: git://git.freescale.com/ppc/sdk/linux.git because it does not working.

Any ideas please???

PS: If I build and insmod in SDK 1.8 it works correctly.

Hello iuro uiro,

Please make sure that the Kernel image and the Kernel module are from the same build.

Please rebuild Linux Kernel and the module with the following procedure.

$ bitbake virtual/kernel -c cleansstate

$ bitbake virtual/kernel -c configure

Go to the folder build_<platform>-64b/tmp/work/<platform>_64b-fsl-linux/linux-qoriq/4.1-r0/build, run the following command to configure Linux Kernel to support the Kernel module.

$ make ARCH=powerpc menuconfig

Go to the build folder to rebuild Linux Kernel.

$ bitbake virtual/kernel -c compile

$ bitbake virtual/kernel

Please build the Kernel module to include the Linux Kernel PATH in build_<platform>-64b/tmp/work/<platform>_64b-fsl-linux/linux-qoriq/4.1-r0/build.

Please boot up the target board with the new built Kernel image and copy and insert latest built Kernel module.

Have a great day,
TIC
