Hello community.
I have a problem when writing compiled code to ESP32. When testing the flash chip, ESPtool shows the following information:


C:\Users\asoko\AppData\Local\Programs\Python\Python313\Scripts>esptool -p COM5 flash_id
esptool.py v4.8.1
Serial port COM5
Connecting...
Detecting chip type... Unsupported detection protocol, switching and trying again...
Connecting...
Detecting chip type... ESP32
Chip is ESP32-D0WD (revision v1.1)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
MAC: c8:2e:18:d2:df:e0
Stub is already running. No upload is necessary.
WARNING: Failed to communicate with the flash chip, read/write operations will fail. Try checking the chip connections or removing any other hardware connected to IOs.
Manufacturer: ff
Device: ffff
Detected flash size: Unknown
Flash voltage set by a strapping pin to 1.8V
Hard resetting via RTS pin...

Where to look? What to fix?

Can you post details about what hardware you're using? (Model of devkit/chip/module, schematics of any custom PCB, connection details etc)

Всім дякую. Проблему вирішено. Як що у когось виникне щось подібне - уважно перевіряйте пайку модуля. В моєму випадку не були запаяні до землі площадки, що знизу модуля.
