#84074 Hello,
What I am trying to do is to flash my esp8266 through another board. The way it works is that the board will operate normally, meaning executing the program that is written in it and and when I want to update it I will drive the pins of the board reset it an flash again. So far the esp8266 has no problem running its AT commands but when I try to set it in bootloader mode it doesn't work. More precisely the error I am getting is:

Serial port COM61
Chip is ESP8266EX
Features: WiFi
MAC: --:--:--:--:--:--
Uploading stub...
Traceback (most recent call last):
raise FatalError("Timed out waiting for packet %s" % waiting_for)
esptool.FatalError: Timed out waiting for packet header
esptool.FatalError: Timed out waiting for packet header

What could be the issue? I believe I am setting the pins correctly.

Thank you for your time.
