I am using iMX 8 Mini EVK for my Project. I build Android 9.0 from AOSP for this board.

Now I want to run a script at boot.

I did following changes in files but still I am facing an issue.


File : Android_AOSP_build/device/fsl/imx8m/evk_8mm/init.rc

service gea3appservice /vendor/bin/sh /vendor/bin/
    class late_start
    user root system
    group root system


File : Android_AOSP_build/device/fsl/imx8m/evk_8mm/sepolicy/gea3appservice.te

# gea3app service
type gea3appservice, domain;
type gea3appservice_exec, exec_type, vendor_file_type, file_type;
domain_auto_trans(init, vendor_shell_exec, gea3appservice)


File : Android_AOSP_build/device/fsl/imx8m/evk_8mm/sepolicy/file_contexts

/vendor/bin/   u:object_r:gea3appservice_exec:s0


When I manually run service I get following error :

[  134.010656] type=1400 audit(1564667688.236:3740): avc: denied { dac_read_search } for pid=1 comm="init" capability=2 scontext=u:r:init:s0 tcontext=u:r:init:s0 tclass=capability permissive=1


Do anyone know this issue?


I tried with the approach suggested by Android developer site

Writing SELinux Policy  |  Android Open Source Project 


But I get following error

libsepol.report_failure: neverallow on line 1002 of system/sepolicy/public/domain.te (or line 11242 of policy.conf) violated by allow gea3appservice gea3appservice_exec:file { execute entrypoint };
