Much like what avrdude does for Arduino uploads, is there any method to have the uploaded sketch verified?
I am using the Arduino IDE with the ESP8266 core and I noticed that it uses esptool to flash the sketch onto the chip.
It doesn't appear to do a verification and I have a couple of modules that are problematic, so I need to ensure that the code is verified.

I looked at preferences.txt located in my AppData|Local\Arduino folder and upload.verify=true.
But there is no indication that it actually performs the upload verification in the console messages.

Many thanks.

Slightly confusingly..there's another esptool: https://github.com/themadinventor/esptool (python script type tool) and this one does have a verify option but it's not used by the arduino core by default.

That's too bad though.
