Create a partition in code

Dear all
Is there a IDF call to create new partition (out of the program code)?
After OTA I want to use a data partition, that the previous FW-Version did not have...
Kind regards
Chris

I found this with a little searching. Is this helpful?

Thank you for the reply.
It's interessting but not what I was looking for. Of course I can modify the Flash using the SPI interface. I was hoping that there's an API in the IDF to create and delete partitions.
Kind regards
Chris

Hello. There in no official higher-level API for this at the moment.

For what it's worth: the reason is that the partition table is not safe to rewrite on the fly: if the partition table gets corrupted because someone switched off the ESP during the write, it can render the chip unbootable.

Dear all
Thank you for the clarification.
I'm not sure where to make that suggestion... or maybe it's stupid anyway.
With OTA there is a similar integrity issue and it has been solved with the ota data partition and two ota partitions. Could that mechanism be used here too?
Regards
Chris

It could, but it's not currently implemented.
