Many thanks to the author of this article. Worth bookmarking.

@ANGU, it seems your module is compiled for thumb2 however it was needed to be compiled for ARMv7. Check in your config file for the settings.

Hey I am getting the error as below:

version magic ’5.0.19-armv7-x15 SMP preempt mod_unload modversions ARMv7 thumb2 p2v8 ‘ should be ’5.0.19-armv7-x15 SMP preempt ARMv7 p2v8 ‘

insmod: ERROR: could not insert module adv7381.ko: Invalid module format

What could be the issue?

Thank you so much for posting this. I had to same problem with the vermagic being socfpga-ltsi vs. socfpga-ltsi-altera. The source code given to me by altera did not match what they preloaded onto the board! Wonderful fix!

I have the opposite problem. Any idea how to resolve it?

Hi Eli

What if turn ON the CONFIG_MODVERSIONS support while compiling the kernel?

I believe this is for those times when we DO NOT have access to the kernel source just the header files. AM I right?

Thank you very much. This article immediately solved a problem that I had during a build/git transition, and where the target busybox insmod did not have a –force option to work around the version mismatch.

hey i have a question on the same matter of versioning:

so i am trying to cross compile the prolific module for mirabox, and i am running into:

pl2303: version magic ’3.2.36 mod_unload ARMv7 p2v8 ‘ should be ’3.2.36 mod_unload ARMv7 ‘

what does the p2v8 stand for and how can i get the versions to match? i am using the same kernel versions.

any help would be appreciated.

thanks

I can’t thank you enough for posting this. Your description of the “gory details” allowed me to complete a compiling project I’ve been working on for some time now. Thanks.
