+When compiling or uploading, the following error may occur:
 
 ```
 Compilation error: Missing FQBN (Fully Qualified Board Name)
 ```
 
-When compiling or uploading code, this error will occur if no board is selected, or if the board core is not installed.
+The error occurs if no board has been selected.
 
-Note that a board needs to be selected even if you're not uploading any code.
+Note that a board needs to be selected even if you're not uploading any code (i.e. clicking ![Verify button](img/symbol_verify2.png) Verify).
 
-## Is a board selected?
+## Select board
 
-Since the code cannot compile without a board selected, we'll start by ensuring just that.
+With IDE 2, you can use the board selector menu:
 
-![The Arduino IDE. The board dropdown displays Arduino UNO, with a red cross.](img/Arduino-Uno_no-port.png)
+* Connected boards that were identified by Arduino IDE will appear in the list.
+* To manually select the board, or to select a board without connecting it, choose _Select other board and port_.
 
-It should be looking somewhat like the above. The name of your board should be visible in the board dropdown bar. There may also be a red cross. This indicates that the board isn't available on any port but this will not prevent the code from compiling.
+![The board selector menu in Arduino IDE 2.](img/board-selector-labels.png)
 
-If it reads `no board selected`, a board needs to be selected. Click to open the dropdown.
+Alternatively, use the _Tools > Board_ menu option:
 
-![The board dropdown open, with no board selected.](img/select-other-board-and-port.png)
+![The 'Tools > Board' menu bar option.](img/tools-menu-board.png)
 
-If you have a board plugged in, and you want to write code for that board, you can choose it in the dropdown. Otherwise, choose 'Select Other Board & Port'.
+See [Select board and port in Arduino IDE](https://support.arduino.cc/hc/en-us/articles/4406856349970-Select-board-and-port-in-Arduino-IDE) to learn more.
 
-![The 'Select Board' window.](img/select-board.png)

-Choose the intended board. You do not have to select a port. Click 'OK'.
+## Install missing boards
 
 If you do not have the associated board core installed, you may receive the following pop-up.
 
 ![The board core installation pop-up.](img/board-core-install-pop-up.png)
 
-In this case, choose 'Yes' to have the required core installed.
-
-## Is the board core installed?
+In this case, choose **Yes** to install the required core.
 
-In the above example, we used the pop-up to install the required core. If you didn't receive a pop-up, or if you're receiving the same error despite a board being selected, please ensure the *board core* is installed using [this guide](https://www.arduino.cc/en/Tutorial/getting-started-with-ide-v2/ide-v2-board-manager#installing-a-core).

+
+A `Compilation error: exit status 1` error indicates that the sketch compilation process has failed, and is not related to the upload process. For more information, look at previous lines in the error output.
+
+For example, check this error output:
+
+```
+.../core_arduino_samd_mkrwifi1010_dc4ffca0ef28855003b5cc223e78a605.a(main.cpp.o): In function `main':
+.../Arduino15/packages/arduino/hardware/samd/1.8.13/cores/arduino/main.cpp:53: undefined reference to `loop'
+collect2: error: ld returned 1 exit status
+
+exit status 1
+
+Compilation error: exit status 1
+```
+
+The most useful information is ``undefined reference to `loop'``, which occurs because the sketch is missing a correctly defined `loop()` function.

+
+`Failed uploading: uploading error: exit status 1` is a generic error message indicating that the upload has failed.
+
+## Check the console output
+
+Often preceding lines will contain more specific information. For example:
+
+```
+No device found on cu.Bluetooth-Incoming-Port
+Failed uploading: uploading error: exit status 1
+```
+
+In this case the `cu.Bluetooth-Incoming-Port` port was selected by mistake. Since no board is connected to the port, the upload failed. This is indicated by the `No device found on cu.Bluetooth-Incoming-Port` message. The issue can be solved by selecting the right port in the _Tools > Port_ menu.
+
+## If you're not sure what's causing the error
+
+Follow these steps:
+
+1. **Check your connections**. Your board needs to be connected with a data USB cable (charge-only cables will not work). Make sure the cable is fully inserted in the port on each end. Try a different USB cable, and avoid hubs and other adapters if possible. Remove connections to the board pins, especially the **0 (RX)** and **1 (TX)** digital pins.
+
+2. **Check your board and port selections**. In the top menu bar, make sure the correct board is selected in _Tools > Board_, and that you've selected the right port in _Tools > Port_. Try disconnecting and reconnecting your board if you're unsure which port is being used (close and reopen the Port menu to refresh the list). For more information, see [Select the right port and board](https://support.arduino.cc/hc/en-us/articles/4406856349970-Select-board-and-port).
+
+3. **Make sure other applications aren't using the port**. Close other instances of the IDE, serial monitors, and any other applications that may be using the port. See [Find and stop process blocking a port](https://support.arduino.cc/hc/en-us/articles/4407830972050-Find-and-stop-process-blocking-a-port).
