Help with debugging "Unable to verify flash chip connection"
Posted: Sun Feb 23, 2025 12:30 pm
Hi folks,
I'm trying to upload a sketch on my ESP32 compiled in the Arduino IDE 2.3.4 under macOS Sequoia 15.3.
With an older ESP-WROOM-32 with a micro-USB connector it's working fine.
With a newer ESP32-WROOM-32D with USB type c connector it's not working.
That's the error message I'm getting:
Any advice is greatly appreciated. If I can supply any other needed info please let me know.
Thanks in advance,
val
