Hi Dominik,

 

For ota update you need to keep ota file on your host PC, the API that you mentioned is used through the adb sideload command.

 

The update sequence is like that:

adb reboot sideload-auto-reboot

wait for reboot of your device (screen remains black)

adb sideload ota.zip

where ota.zip is the name of your ota file.

Please note that you can use “adb reboot sideload” instead of “adb reboot sideload-auto-reboot” which is similar to previous command but does not automatically trigger reboot at the end of update, and it also does not display the update animation.

 

Regards.

Philippe

Hi Philippe,

 

That is correct, I forgot the SPARSE_IMG.

 

Do you know where I have to put the OTA file in order for it to work via the android/os/RecoverySystem api (installPackage)

 

Best regards,

Hi Dominik,

Can you please check and confirm the command line you are using?
Instead of:
make dist
it should be something like that:
make SPARSE_IMG=true dist -j8

I suspect that you might have forgotten the parameter SPARSE_IMG=true in your command line, which might explains why you get error in __init__ function of sparse_img.py.

Hi all,

?make dist?  produces the following error:
