Update all flash data in one go?

[MartinDavidWaller]

Hi, I have a question if I may? I've tried out ElegantOTA and it works as expected for both the firmware and the file system. I was wondering if I use a command similar to:

esptool.exe --chip esp32-c3 --port COM8 --baud 921600 read_flash 0 ALL flash_content.bin

This reads all the flash data, including the file system, and saves it in one file.

Can ElegantOTA then be used to upload that one bin file so that the firmware and file system get updated at the same time?

Many thanks

Martin

This is not possible : Elegant OTA relies on a traditional partition scheme where there are 2 app partitions : one in use and one updatable (OTA update will switch the role of these 2 after boot time).
Flashing from 0 will overwrite the currently used partition and will crash.
Flashing a factory partition (like you do) has to be done through usb or through a recovery partition, a little like MycilaSafeboot is doing (but would require to be adapted to remove the starting partitions and only keep app and de)
