#include esp32-hal.h (in hardwareserial.h) no such file

[Sjaako]

I recently used arduino IDE to programm an ESP32 succesfully.
After that I had to upload a programm to some Arduino Nano's .
Selecting the AVR nano and the bootloader i get the above error.
whats wrong?
Selecting my esp32 project and compiling works fine.

When you encounter an error you'll see a button on the right side of the orange bar in the Arduino IDE "Copy error messages". Click that button. Paste the error in a message here using code fencing.

It looks like you somehow replaced or corrupted your Arduino AVR Boards platform installation when you installed the ESP32 boards platform.

Since this is caused by a non-standard use of 3rd party software, rather than a bug in official Arduino software,
this topic is more appropriate for the Arduino Forum. I'm sure we'll be able to help you with your problem over there.

Please do this:

1. Read http://forum.arduino.cc/index.php?topic=148850
2. If you haven't already done so, create a new thread in the appropriate section of the forum (http://forum.arduino.cc/), following all the rules. Be sure to post that full error, using code tags (</> button on the toolbar).
