Hello, I’m following the Learn LVGL for ESP32 book but I get a fatal error when trying to download to the CYB.
Afatal error occurred. Unable to verify flash chip connection (serial data stream stopped: possible serial noise or corruption.)
I purchased two of these boards from Amazon and they’re both doing the same thing. I tried two different cables but no luck. I’ve checked my library versions and they match what you suggested to install. I’ve also tried pressing the Boot button while downloading.
The boards display a sample program when they are powered up so they seem to be working ok.
When I select board info it says Unknown Board, VID: 0x1a86, PID: 0x7523. The back of the CYB says ESP32-2432S028.
Any help would be greatly appreciated. Thank you.

Hi.
You may need to install the CP2101 or CH340 drivers on your computer.
What is the chip on your board? Usually for these boards is the CH340 USB driver you need to install.

Hmm, I never thought that my computer was the problem. I’m running Linux Mint on an older MacBook Pro. Are these drivers still compatible?
Thank you.

Yes, I think so.
Are you able to upload code to any other ESP32 board?
