Android13 GKI Unknown symbol

Leo-Ze — Tue, 02 Apr 2024 01:01:48 GMT

Hello,

I'm currently on the imx8mp with Android 13_v1.2.0 and hit a snag with the GKI export symbol failing.

I have integrated an out-of-tree LTE driver, and after referring to the User Guide(included the necessary settings in imx8mp_gki.fragment and ShardBoardConfig.mk).

Additionally, after updating the abi_gki_aarch64_imx & abi_gki_aarch64.xml as per UserGuide section 9.5 and reflashing,I still encounter messages like "Unknown symbol."

Could you provide a more detailed approach or possible reasons for this error?

Thanks.

Hi @Leo-Ze

Have you finish the 9.4 How to export new symbols? You need update abi_gki_aarch64_imx first and then update abi_gki_aarch64.stg.

Best Regards

Hi Zhiming,

I referenced the following step: Export-new-symbols

The abi_gki_aarch64_imx and abi_gki_aarch64.xml files have been updated,

then I copied the abi_gki_aarch_imx and abi_gki_aarch64.xml files to the NXP kernel directory:

"android_build/vendor/nxp-opensource/kernel_imx/android/"

and after recompiling and flashing, the "Unknown symbol error" still appears during boot-up, as shown in the previous image：

qmi_wwan_q: Unknown symbol netdev_stats_to_stats64 qmi_wwan_q: Unknown symbol arp_create

Additionally, I would like to inquire about the step "update abi_gki_aarch64.stg".

What does this step entail? I couldn't find any relevant information in the User Guide.

Thanks.

Regards,

Leo Wang

Hi Zhiming,

now I use is android 13 (kernel 5.15), According to user guide...

I think is the same thing(abi_gki_aarch64.xml)?

If so, then despite updating the abi_gki_aarch_imx and abi_gki_aarch64.xml files

I'm still encountering the "Unknown symbol" issue.

It seems like I might have missed some crucial steps...

Could you please provide a more detailed approach?

Thanks.
