I can't program or open the console on my ESP32-C3-MINI-1

[troymitchell]

As the title says, I designed a circuit board, soldered the necessary components (ESP32, LDO, USB), and found that /dev/ttyACM0 can be recognized but cannot perform any operations. Can anyone help me?

For the first flash, you may need to either have luck with timing or lower GPIO0 while resetting the module. Without valid flash, the ESP32C3 will enter a bootloop which can make it hard to get the flash timing right; booting with GPIO0 forces download mode which bypasses this.

This is so weird. When I used the ESP32-C3-FN4 chip, everything was fine for the first flash.
This time, due to the problem of the workplace, there is no good welding equipment, so I chose the module, but I was disappointed that I had to take my chances for the first download.

finally,
I held down the reset button, and then let go of it at the moment of downloading, and everything was fine. Thank you very much for giving me ideas.
