Customer:
I have an Inkplate 6 that I’ve been using to build a door sign that loads a calendar. The board was working, but now uploading code fails with this error:
A fatal error occurred: Unable to verify flash chip connection (Invalid head of packet (0xE0): Possible serial noise or corruption.).
Failed uploading: uploading error: exit status 2
Any ideas what’s causing this?

Soldered Support:
If the board operates but won’t let code be uploaded, it’s likely a communication issue rather than a hardware failure. Try these troubleshooting steps:
- Use a different USB cable and different USB port, preferably USB-C
- Check if you have connected anything else to the board - sometimes a short can interrupt serial communication
- Check if the board appears in your device manager as a Serial COM port (you can see this in Arduino)
- Lower the upload speed to 115200 in the ‘Tools’ menu
Try these and let me know if the upload works.

Fixed it - the issue was a bug in the WiFi-HTTP-Result code, bad programming, and the upload speed setting.
