OTA - upload over the internal flash as temporary storage

[sergioxdev]

Hi Guys

I am trying to be able to run an ota, saving the new firmware on the internal flash memory and on resetting the device, run the OTA.
This is an example where the new firmware is downloaded and saved on the internal memory and when restarted it is loaded:

any suggestions :)
