It’s not my first Arduino, or my first ESP32 chip. I’ve followed the directions in the hookup guide but haven’t been able to upload any code to the board. I get the following message:
“A fatal error occurred: Unable to verify flash chip connection (Packet content transfer stopped (received 6 bytes)).”
Any hints why this might be happening? Is the board defective?
If none of that changes anything it is likely defective; head to www.sparkun.com/returns if purchased from us (or vendor for similar) for a replacement (but please complete the above steps first)
