Flashing without entering Download Mode?

[pptzpp]

At some point my dev board (ESP32-C3-mini-1) stopped flashing.

Code: Select all

idf.py -p /dev/ttyUSB0 flash

just wouldn't connect. After a while I accidentally discovered that if I don't put the board into download mode by holding the Boot button and pressing the RST button, then the flashing does go through. Weird, I thought, but whatever. The problem is that since then I began experiencing unexpected behaviour of the application. I cannot be sure it's related in any way, but it was enough to make me think. Don't know if I can get any help, but I thought I'd try. I'm on a Linux guest inside a Windows host.

Possibly a power issue? Did you happen to use a different cable than before? (Note that VMs are known to mess up the timing needed for the auto-reset circuit, so some weirdness getting into download mode is to be expected.) Also, what unexpected behaviour are you getting?

So you mean auto-program fails, right? If the error is sync problem or there are other erros?
