Custom Service is not running on IMX8QM-Android 9

vinothkumars — Tue, 05 Nov 2019 13:06:56 GMT

Dear NXP,

I am working on IMX8QM with Android 9. Currently, I am using imx-p9.0.0_2.1.1-auto-ga source. I added new service but, the service is not started automatically. So, I start the service manually then I got error,

mek_8q:/ #
mek_8q:/ # start usb-update
[ 192.968153] init: Received control message 'start' for 'usb-update' from pid: 3747 (start usb-update)
[ 192.977574] init: No such service 'usb-update' for ctl.start

Thanks & Regards,

VinothS,

Hello,

Unfortunately, the creation and implementation of Android services are out of the scope of our free support. You could go with professional service support. They could help you with this problem. I apologize for the inconvenience this could give you.

Best regards,

Hi,

Custom service started probably but, I got error and service exit.

SELinux: Context u:object_r:usb-update_exec:s0 is not valid (left unmapped)

mek_8q:/ # start usb-update
[ 442.362348] init: Received control message 'start' for 'usb-update' from pid: 3538 (start usb-update)
[ 442.371635] init: starting service 'usb-update'...
[ 442.377693] init: cannot setexeccon('u:r:usb-update:s0') for usb-update: Invalid argument
mek_8q:/ # [ 442.386918] init: Service 'usb-update' (pid 3539) exited with status 6

Thanks & Regards,

Hi,

This is the final configuration working for me,

1. Set Selinux policy to permissive mode,

Path : device/fsl/imx8q/mek_8q/BoardConfig.mk

BOARD_KERNEL_CMDLINE += androidboot.selinux=permissive

2. Create the service,
Path : device/fsl/imx8q/mek_8q/init_car.rc

# Start the service
start usb-update

# Provide the root permission to the script
exec - root root system -- /system/bin/usb-update.sh

# start the usb-update service
service usb-update /system/bin/usb-update.sh
class main
user root
oneshot
seclabel u:r:init:s0

3. For Adding the custom service,

Path : device/fsl/imx8q/mek_8q/mek_8q.mk

PRODUCT_FULL_TREBLE_OVERRIDE := false

4. For execute the service,
Path : device/fsl/imx8q/sepolicy/file_contexts

/system/bin/usb-update.sh u:object_r:init_exec:s0

Thanks & Regards,

VinothS,
