Troubleshooting
Freedom Studio
Below is an issue that you may run into when using the RED-V in Freedom Studio.
Issues Uploading to the RED-V Again
There are a few reasons why if you have problems uploading code. If you recently uploaded code and the board is still connected to your computer, you'll need to make sure to hit terminate (i.e. the button that looks like a red square) before uploading again. This is because Freedom Studio is still connected to the board in debug mode.
If you uploaded several times to the board and have issues uploading after clicking on the terminate button, try disconnecting the RED-V from your USB port. Then re-insert the board back.

Issues Compiling
