Hi
I bought a new board ESP32-TTGO-CAMERA  SSDD1306 PIR and I’m used to develop in python
I wonder that If I can flash the original firmware and upload this:
http://micropython.org/resources/firmware/esp32-idf4-20200403-v1.12-331-ge97bb58f0.bin
and it works all programs that has originally, such us connect
Should I upload new micropython libraries?
and how can I backup original firmware?
Regards

Hi.
I’m not sure if I understood all your questions. Please, clarify if I haven’t answer all the questions.

You can upload MicroPython firmware to that board and program it with MicroPython.

After that, if you want to program it using Arduino IDE, you just need to upload a new code using Arduino IDE, and it will wipe out the MicroPython firmware from your board.

If your board comes with examples from factory, I don’t think you can get them and save them on your computer to upload them later.

I hope this is clear.

Hi Sara,
I think that you understood what I mean.
…If your board comes with examples from factory, I don’t think you can get them and save them on your computer to upload them later…….
 
this esp32 ttgo device, has a examples from factory. I can connect my laptop to a esp32 wifi and check that camera works properly. I don’t want to lose this example, and roll back, when I want.
if you think that I could not restore a backup firmware+examples code, you can close this question.
Thanks for you response.

Hi.
Rui told me that it is possible to get the .bin file that is currently on the ESP32. Then, you can upload it later. If you want.
You can do that using esptool. I’ve never tried that, so I’m not sure if it works well for this.
I’ve found this tutorial that might be exactly what you are looking for: http://www.cyberblogspot.com/how-to-save-and-restore-esp8266-and-esp32-firmware/
I hope this helps.
