iMX6q sabersd OTA update

[Babu]

Hi,

I am trying to update ota images over USB, as mentioned in Verification OTA w/ update.zip and diff-ota.zip for imx6 sabersd (android 6.0.1). But not able to see "upgrade successful." message on the console And changes also not reflecting.

Below are the steps i am following,

1. $source build/envsetup.sh

2. $lunch sabresd_6dq-user

3. $make

4. Flash the generated images using mfgtool

5. Do changes one of the packages

6. $make dist

7. cp out/target/product/sabresd_6dq/sabresd_6dq-ota-20160331.zip /media/usb/ (copy from Host to USB device)

8. cp /mnt/media_rw/USB/sabresd_6dq-ota-20160331.zip /cache/

9. $echo --update_package=/cache/sabresd_6dq-ota-20160331.zip > /cache/recovery/command

10. $reboot recovery

After step #10 system halting for some time with the below logs

init: Starting service 'recovery'...
EXT4-fs (mmcblk3p6): Ignoring removed nomblk_io_submit option
EXT4-fs (mmcblk3p6): mounted filesystem with ordered data mode. Opts: nomblk_io_submit

EXT4-fs (mmcblk3p6): mounted filesystem with ordered data mode. Opts: nomblk_io_submit
SysRq : Emergency Remount R/O

reboot: Restarting system with command ''

Please let me know if anything wrong in the above steps or is there any other way to flash in new versions of android.

Thanks in advance.

Hi igor,

Thank for your reply...

As mentioned in Documentations i have done below experiments.

1. Built OTA images using

       a)  make otapackage

       b)  make PRODUCT=sabresd_6dq-user otapackage -j4

OTA package is generated in "out/target/product/sabresd_6dq/" as "sabresd_6dq-ota-20160331.zip"

copy the above package in /cache and run the below commands to start update.

# echo “--update_package=/cache/sabresd_6dq-ota-20160331.zip\n--locale=$(getprop ro.product.locale.language)” > /cache/recovery/command

# reboot recovery.

With Other procedure system is not booting as mentioned in the Initial posting.

2. Generate OTA Package from the target files as mentioned below

# ./build/tools/releasetools/ota_from_target_files.py out/dist/sabresd_6dq-target_files-20160331.zip ota_update.zip

unzipping target target-files...
(using device-specific extensions from target_files)
loaded device-specific extensions from /tmp/targetfiles-dAMf3n/META/releasetools.py
using prebuilt recovery.img from IMAGES...
using prebuilt boot.img from IMAGES...
putting script in bin/install-recovery.sh
no bootloader.raw in target_files; skipping install
done.

In this procedure kernel is not able to find the DTS files, hence it is rebooting continuously with below logs.

For the Flattened Device Tree issue, try updating the boot.img in the update.zip with the new boot.img generated by the build scripts.

[igorpadykov]

link Verification OTA w/ update.zip and diff-ota.zip is for r13.4.1

and may not work for android 6.0.1.

[Babu]

can you please elaborate "link Verification OTA w/ update.zip and diff-ota.zip is for r13.4.1" ..

Is ts tested in any of the freescale imx6 series. If so, can you please share the repo link.

Hi Igorpadykov,

I have been following the same procedure to  build recovery.img to perform OTA operation, but i'm not able to generate recovery.img. I tried some changes in Make file in /build/core, still the result is fail!!. Any one in conversation can help me out..i have attached Make file from /build/core. Please have a look and come back.

This is results after the command make otapackage:
