I dont know about FSLOTa nor do I know about the device you are working on. But If you want to implement your own OTA process you could try the following (Just a short draft since your question is very broad):

1. Create a system app that checks from time to time your server for new packages.
2. if it detects a new package it downloads it to your device.
3. it copies the downloaded update.zip to /cache/
4. Then the app creates the following file /cache/recovery/command and writes --update_package=path_to_your_file in it. (For more commands see /bootable/recovery.cpp)
5. Then it forces a reboot into recovery
6. recovery installs your ota package.

Update: I quickly checked the app you linked. I would check these things:

1. Do you get till the point where RecoverySystem.installPackage() is called ? (https://github.com/embest-tech/android_packages_apps_fsl_imx_demo/blob/master/FSLOta/src/com/fsl/android/ota/OTAServerManager.java#L282)
2. Do you see a message in logcat from the RecoverySystem that it is going to reboot? (maybe you have a permission problem and your app is not allowed to force "reboot recovery")
3. Is the path to your update.zip correct? (it should be in /cache/)
