Cannot upload to IoT RedBoard ESP32 Development Board

I just purchased the IoT RedBoard ESP32 Development Board. I’ve tried several times to upload the blink sketch, but I keep getting the following error: A fatal error occurred: Unable to verify flash chip connection (Packet content transfer stopped (received 6 bytes)).

I’m holding the boot button each time. I’m using a Mac with the latest IDE… My serial port connection works with other boards. I would appreciate any help.

Try ensuring the drivers are installed https://learn.sparkfun.com/tutorials/ho … -need-them and see if that changes the behavior?
