Hello,
We are planning to use the Firefly ROC-RK3566-PC (https://en.t-firefly.com/product/industry/rocrk3566pc.html) platform board for one of our IoT project.
We we're planning to go for Android 11 OS for the same board and had the following queries:
1.Will Firefly provide long term support for the following platform board(ROC-RK3566-PC)
2. Is OTA support available after Android 11.(for future releases like Android 12).
3.Can we have access to the Android 11 source code ? As for our activity we need to port the changes from our existing platform to Firefly platform.
