ESP32 Forum

Hello, I have a problem uploading code to esp32-h2-wroom03 I can't upload

I have tried the 10k pullup resistor at EN and pressed the button before uploading. Unable to upload


The debug I use (usb to ttl) I'm using CH340.
I continue as follows:
module usb to ttl
VCC <--------> 3.3
GND <--------> GND
TX <-----------> RX
RX <-----------> TX
Initially, you can read data from the serial monitor that the board has previously uploaded data to. The board can still be used.

The error that I know is The signal line has a disruptive signal.

Wrong boot mode detected (0x1d)! The chip needs to be in download mode.

if i use arduino ide i must chose board ?
please advise me

Did you indeed check the troubleshooting link in that error?

i not sure about Boot Mode Selection i read datasheet i pulled-up 3.3V with resistor 10k at EN pin then i check button when press it 0V but can't flash program and i pushed and released 1 time boot button but can't uploaded.

if you have wiring for esp32-h2-wroom03 or video tutorial It a good for me .. thank for reply

Have you tried pressing the boot button while uploading the code?

Yes i tried.

Then we need more info. Can you post the schematic for the PCB you use that the Wroom module sits on?
