Upload problems

Uploading to ESP8266 is somtimes a nightmare. Only after several retries upload starts, and somtimes only at a very low speed.

When viewing output from the upload I can find the compiled .bin file, and I tried to upload this using the expressif tool flash_download_tools_v3.6.5.exe. (Arduino IDE uses ESPTOOL.EXE)

It not only uploads the first time I try, but I can also set upload speed to 1,500,000 bps - and still uploading first time.

Is it possible to change the Arduino IDE installation (ESP8266 device) to use the expressif tool?

This is output from ESPTOOL.exe (sucsessfull after several retries);

Reopening as I didn't catch that there were two outputs. I don't think others are seeing your issue, though, so you may want to make sure you're running the latest 2.5.0-dev2.

#5635 replaces esptool-ck.exe w/esptool.py, the one that Espressif maintains, so that PR would close this.

Closing as #5635 merged. esptool.py seems much more resilient for uploading on my own HW.
