Posted: Thu Nov 11, 2021 1:08 pm
Hi everyone!
I have next problem with my proprietary pcb, where ESP32-PICO-D4 is used. Schematic of my board is in attachments.
I can not program my board (tried throug arduino and esp-idf). every time I have the same problem:
A fatal error occurred: Serial data stream stopped: Possible serial noise or corruption
Arduino IDE log there:
I dont know why my board is defined (see string with mcu name), but i can not upload any firmware, even empty sketch.
I have already tried:
Does anybody know what can I do with this issue?
Thank you! I hope I didnt broke the forum's rules with this post.

I have already tried:
- Add 10uF cap to EN net
- Short BOOT to GND when connecting
- Pull-down RX line (try to reduce possible noise in line)
Does anybody know what can I do with this issue?
