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. Wh...

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? https://i.postimg.cc/85Z0sjL9/2024-12-01-16-49-35.png https://i.postimg.cc/0Nnsd5pd/2024-12-01-16-5...
