Vue 3 - Unable to flash - Help requested

[gbuntin]

I recently bought 2 Emporia Vue 3 systems and am unable to flash them to Esphome. I was able to backup the firmware.

I've tried multiple configurations and it always fails with the same errors so I'm hoping that it isn't a config issue. (one sample config that I tried can be found here #264) YAML file attached as Emp1.txt

Any thoughts / assistance would be fantastic.

The command I'm using is:

esphome run Emp1.yaml

Here is the error I get:

Warning: Image file at 0x1000 is protected with a hash checksum, so not changing the flash size setting. Use the --flash_size=keep option instead of --flash_size=8MB in order to remove this warning, or use the --dont-append-digest option for the elf2image command in order to generate an image file without a hash checksum

The full message when attempting flashing after choosing the com port.

Here is some more information I've gleaned by running various other commands:

espefuse dump --port com8

attached as empDump.txt

espefuse summary --port com8

Emp1.txt

I managed to figure it out.

I added flash_size: 8MB to the esp32 section of my Yaml file:

esp32:
board: esp32dev
flash_size: 8MB
framework:
type: esp-idf
version: recommended
