Kernel Drivers/Modules from gki.fragment Not Loaded After OTA Update in i.MX8MQ(Android14_2.0.0)

Maruti — Mon, 02 Jun 2025 06:00:07 GMT

Dear Team,

We are working with Android 14_2.0.0 on a custom board based on the i.MX8MQ platform. We are including our drivers and kernel modules using a gki.fragment configuration.

Issue Description:

Before OTA Update:
- The board boots from the boot_a slot.
- All drivers and kernel modules defined in gki.fragment are correctly loaded at boot.
- Functionality dependent on these modules works as expected.
After OTA Update:
- The board boots successfully from the boot_b slot.
- However, none of the drivers or kernel modules from gki.fragment are loaded.
- This causes critical features relying on those modules to break.

Additional Information:

GKI Kernel Version: 6.6.30
Kernel Version Before OTA: 6.6.30-4k-g83331275a61f-dirty
Kernel Version After OTA: 6.6.30-android15-8-g63f82df87330-ab12046046-4k

Could you please help us identify what might be missing or misconfigured? We need a solution to ensure that the gki.fragment modules load correctly after an OTA update.

Regards,
Maruti Naik

please check

1. device/nxp/imx8q/mek_8q/SharedBoardConfig.mk

please make sure all the modules you added are listed in this file

2. This file (SharedBoardConfig.mk)

divides the storage locations of the kernel modules into two parts : one is inside the ramdisk. and the other is in the vendor_dlkm partition.

You can check the directories $OUT/vendor_ramdisk/lib/modules/ and $OUT/vendor_dlkm/lib/modules/ to see if the files you need are there.

Regards

Daniel

Hi Daniel,

Yes, I have checked — the modules are present in the vendor_dlkm/lib/modules directory.
With normal binary flashing, all the modules load without any issues.
This problem occurs only after the OTA update.
