Customer:
I purchased several Croduino NOVA32 boards, but I have the same problem with all of them. When I try to upload code to any of them I get the following stack trace:
esptool.py v2.6
Serial port /dev/ttyUSB0

Chip is ESP32D0WDQ5 (revision 1)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None

A fatal error occurred: Timed out waiting for packet header
A fatal error occurred: Timed out waiting for packet header
The same problem occurs on both computers where I tested it.
For the board I set ESP32 Dev Module, as mentioned in the answer to someone’s question on the product page, and didn’t change anything else.

Isti problem događa se na oba računala na kojima sam isprobavao.
Za board sam stavio ESP32 Dev Module, kao što piše u odgovoru na nečije pitanje na stranici proizvoda, ostalo nisam mijenjao.
