[vinothkumars]

Dear NXP,

I am working on IMX8QM with Android 9.  I got following error when do OTA update. Coped update.zip file in cache folder. 

OTA update failed after reboot recovery.

E: couldn't load bitmap progress_empty (error -1)

E: couldn't load bitmap progress_fill (error -1)

E: couldn't load bitmap stage_empty (error -1)

E: couldn't load bitmap stage_fill (error -1)

E: couldn't load bitmap installing_text (error -1)

But, I checked the files under the path the files are present,

out/target/product/mek_8q/recovery/root/res/images

Icon_error.png

progress_empty.png

progress_fill.png

stage_fill.png

stage_empty.fill

installing_text.png

But, I am not getting load error from Icon_error.png .

These are following observations,

1. copy the update.zip file into cache folder and reboot recovery,

reboot: Restarting system with command 'recovery'

2. Simply reboot without update the android images,

reboot: Restarting system with command ''

3. Check the boot log,

Update is not done (check build ID and date and time of android images).

Hi,

I have some of the question related to OTA update in IMX8QM - Android 9 Automotive.

1.  Which one I want to follow for ota generation from section 7.

      android_p9.0.0_2.1.1-auto-ga_doc/Android_User's_Guide.pdf

2. For OTA update, which package do I need to take ?

       mek_8q_car-target_files-eng.emb-vinosek.zip

       mek_8q_car-ota-eng.emb-vinosek.zip

3. Sometime with display ota update not happens, 

4. what is the deference between "/cache"  and "/data/cache".

Thanks & Regards,

progress_fill.png

stage_fill.png

stage_empty.fill

OTA BUILD,

source build/envsetup.sh

lunch mek_8q_car-userdebug

make otapackage -j4

OTA files are,

       mek_8q_car-target_files-eng.emb-vinosek

       mek_8q_car-ota-eng.emb-vinosek

But, I use userdebug but, ota build for eng.

Thanks & Regards,
