ESPFlashDownload is used to download a local file to ESP32.
I'm looking for the other direction, I need to download a data partition from ESP32 to a local .bin file
The .bin file, ceated this way will be downloaded to other ESP32, or to the same ESP32 after erasing flash.
Download partition from ESP32 to local .bin file
Re: Download partition from ESP32 to local .bin file
I'm not familiar with "ESPFlashDownload". Is that similar to esptool?
Using esptool we can retrieve data from ESP32 flash.
For example
esptool read_flash {address} {size} {targetFile}
will retrieve data from a serial connected ESP32 at offset address for size bytes and write it to the given file. Is this what you are perhaps looking for?
