I have Kernel 4.1.15 + File System "Jetro" ( 2015 ) - module galcore.ko working OK , no problem with "insmod galcore.ko"
I did update to kernel 4.1.52 + File System "Jetro" ( 2015 ) - module galcore.ko working OK , no problem with "insmod galcore.ko"
I compiled 2 version galcore.ko ( external module ) - with kernel 4.1.52 & kernel 4.14.98 & File System "Sumo" ( 2019 / 4.14.98 ) & I have the same problem:
If I use version from kernel 4.1.52 - I get a message - problem with version.
If I use version from kernel 4.14.98 - I get a message - problem with version.
About problem with galcore driver:
Did I understand correctly - versions Kernel must match one another version FS (BSP), for example:
Kernel 4.14.98 + FS "Sumo" (4.14.98 ) ?
Kernel 4.1.15 + FS "Jetro" ( 4.1.15 ) ?
You don´t have to compile galcore in L4.14.98 since this is a BSP version, you must have galcore present. Please remove everything and download the BSP again.
For the 4.1.52 I don´t understand you say it work and the you said it doesn´t. However this is not kernel version supported.
