ESP32-C3-MINI-1 programming

[gfeller]

Hi,
I got into a problem when trying to program the ESP32-C3-MINI-1 module on my electronics.
Programming software: flash_download_tool_3.8.8
When I checked with a terminal emulator on the debug port (I want to use for programming as well), I see the following:
ESP-ROM:esp32c3-api1-20210207
Build:Feb 7 2021
rst:0x1 (POWERON),boot:0x0 (USB_BOOT)
wait usb download
Is there a bootloader version that only supports firmware download over USB ?
I never had this problem before (always connected my modules over UART 0 for FW uploads), and the USB pins are not routed on my electronic.
Thanks for any ideas that may help!
BR, Martin

I think you should make sure your bootstrap (strapping) pins are set correctly, that seems to be the issue here. Refer to the ESP32C3 datasheet for the correct pins and settings.
