Writing twice to flash via USB with same baudrate

ESPHome
1

After understanding that “esphome run” tries to first write the firmware at a too high baudrate, I added the following lines to the yaml:

esphome:
  name: esptest
  friendly_name: "ESP32 Test"
  platformio_options:
    upload_speed: 115200

Still, it writes the firmware twice:

Why does it say

INFO Upload with baud rate 115200 failed. Trying again with baud rate 115200.

?

Writing it only once would
a) save time
b) enhance lifetime of the flash memory.

How can I achieve this?

I have the same problem.

That warning is probably your answer.

It appears you have told it to use the lower baud rate. I have to do that with my older m5 stack devices, because they don’t support working faster, but they do reset properly at least.

I don’t know how you set the no_reset option using platformio, but I would guess it is easy enough to find by searching. I would do that and then remove setting the baud rate, unless you also know your device doesn’t work at the higher rates.
