Hello @KeepGoingZouZou,
USB-TTL 3.3V/5V USB-TTL(TX)->ESP32S3(RX) USB-TTL(RX)->ESP32S3(TX) CH340 3.3V/5V CH340L(TX)->ESP32S3(RX) CH340(RX)->ESP32S3(TX)
Does this mean that USB-TTL 3.3V/5V = CH340 3.3V/5V? I don't understand why you mention two configurations.
1) Are you using the correct serial port? On MacOS, USB-to-Serial bridges usually appear as a /dev/cu.usbserial
device. Your log shows /dev/cu.usbmodem
- which usually appears when you connect to the internal USB-Serial/JTAG or USB-OTG peripherals of the ESP.
2) You mention you can enter the burn/download mode
, can you really see the waiting for download
prompt in the serial log? How do you enter the download mode? The bare ESP32-S3 module has no BOOT and RESET buttons - meaning you can't perform a manual reset to bootloader. Also, you do not mention any connection to the boot strapping pins (DTR -> GPIO0, RTS -> EN pin) - meaning an automatic reset cannot be performed as well.
Closing this for inactivity.
