Usage of Filesystem

Hi forum,
we are using the QCA4020 and the qapi functions for the filesystem. I have some general questions about the behavior of the filesystem that I can not find the answers in the documentation:

  1. It seems that the filesystem is overwritten/erased everytime I flash a new image via JTAG or USB. We are currently in development mode and do this several times a day. Is there a way to keep the existing filesystem content during that flashing procedure to continue the testing with the previous content?
  2. What happens with the filesystem during OTA? I read something about a secondary filesystem in the documentation. I hope that the existing filesystem content is still available for the new image flashed via OTA. Can you please clarify on that?
  3. During production line flashing: Is it possible to flash a preset filesystem to the SoC? Which means that some of the files have already an initial content.

Thanks for the answers and best regards

Andreas

>> Yes, Use "SET FS1IMG=KEEP" to keep the existing filesystem content during that flashing procedure.

>> Secondary File System is used to copy the OTA image during transfer,  the existing filesystem content will be still available for the new image.

>> Yes, QCA4020 support of flashing preset files during flash.
