OTA and Memory partitions

Postby Palonso » Tue Sep 24, 2019 9:08 pm

Hi,

I'm trying to update my ESP-WROOM-32D (DevKit) firmware through OTA, yet the results I get is that I can update the firmware only once and then the new firmware seems to override the previous OTA firmware and can't update any more unless I connect it to the PC with a USB.

I'm using the native_ota example from github and followed the steps to mount a server on my computer with the hello-world example code, the only thing I change is the PROJECT_VER variable from 1 to 2 (I also changed the print to "hello world version 2") so the native_ota example download and upgrade the firmware.

My biggest doubt in this is:
I have to add the OTA update code feature in the hello-world code too so I can keep updating (let's say to a hello-world version 3)?
Or is there some way to start the program from the factory partition check for updates and then change to the corresponding OTA to run the main program?

this is what i get in the monitor from what i have already done:

Code: Select all

Re: OTA and Memory partitions

Postby chegewara » Sat Sep 28, 2019 3:13 am

What you see is normal behavior.
My biggest doubt in this is:
I have to add the OTA update code feature in the hello-world code too so I can keep updating (let's say to a hello-world version 3)?
Or is there some way to start the program from the factory partition check for updates and then change to the corresponding OTA to run the main program?
Thats correct, you have to add OTA code to every app, even hello-world, if you want to perform OTA update more than just one time.
