Code doesn't uploing on my board

Postby Seweryn_ » Fri Jun 09, 2023 11:50 am

Hello,
I just bought an ESP32S chip with universal board and soldered it according to the documentation but when i trying to upload the code using the 8622 board i getting an error
Timed out waiting for packet header
I connected the pins as follows:
ESP32:
EN -> r 10k -> 3.3v
GPIO0 -> r 10k -> 3.3v

after several failed attempts i added capacitor 10uF between EN and GND pin but it fault so i tried add next serial capacitor 100uF

ESP8622:
EN -> GND

ESP32 to communication with ESP8622 programmer:
32 RX -> 8622 TX
32 TX -> 8622 RX
32 3.3v -> 8622 3.3v
32 GND -> 8622 GND


I checked the circumferential continuity and all was fine so i don't know where i took a mistake :|

I'd think you need to connect TX to TX and RX to RX in this case, as the silkscreen has the ESP8266 designation for the pins on it, not the usb->serial converters. Also, note that IO0 needs to be low on reset if you want to flash the module.
