Help for ESP32-C3 boot mode
Posted: Fri Apr 28, 2023 7:04 pm
Hi.
I have made some custom board with ESP32-C3 -WROOM-02 module shown on the attachment.
I have problem setting the ESP32-C3 in boot mode.
i have set the gpio pins like documentation strapping pins:
GPIO-2 -> HIGH
GPIO-8 -> HIGH
GPIO-9 -> LOW
3V3 is set to 3.3V
GND pin is set to GND
EN pin is set to HIGH throu 10K resistor.
i connectet my USB to UART like:
3V3 -> 3V3
GND -> GND
RX -> TX
TX -> RX
I am trying to get in boot mode by connecting EN pin directly to GND for couple of second and releasing.
But i cannot get in boot mode.
i am trying to read the chpip id with esptool by:
esptool.exe chip_id
but i always get an error: A fatal error occurred: Failed to connect to Espressif device: No serial data received.
The only data that i recive is #00 when i am doing reset.
USB to UART is ok, i can enter boot mode on other ESP32 boards.
Can u pls help me identify the problem.
Thanks.
