vlan.tar.xz (27.9 KB)
I am suspecting , I may have missed in mdef. Could you please help me with this. I have attached source of driver
the source code is different, that is why it will have different behavior
Have you recompiled the new one?
I have taken source from yocto build , and recompiled using mdef in mangoh github link source code with legato 11.2 toolchain . Still the errors is same. Hence unsure about the process I am following is correct using mdef. I am not getting errors when I used in-tree module using yocto build image.
if you suspect the mdef method has problem, you can directly modify Makefile and just use the toolchain to make the driver.
Here is an example of compiling the kernel driver with toolchain only:
This method tried earlier, compilation failed. Could you please confirm include path for this method.
I can see segmentation fault here:

Seems it stops at vlan_proc_add_dev() in vlanproc.c…
have you added debug message to your driver to see why it crashes?
BTW, why you cannot upgrade the yocto.cwe if it already works?
Does this means that these many dependencies are there?

no idea, i am not expert in vlan, but it could be the problem.
BTW, why you cannot upgrade the yocto.cwe if it already works?
We are using ipk method for upgrade.
I have no experience on IPK method…
Good luck!
BTW, what is the reason that you cannot use normal method to upgrade yotco.cwe?
