Auto flashing error (GPIO0 need to be manually set low)

[newsettler_AI]

Hello!

I'm using ESP32 DOIT kit. I flashed it automatically with onboard CP2102 usb-uart converter.
But once I got app crash (says CPU halted) I'm not available to flash it in auto mode.

Now I have to hold GPIO_0 on ground untill flashing will be done, even with fixed code its not flashing automatically anymore.

I cant get what happens, since there wasnt any hardware errors

How can I fix it?

Probably one of your two transistors is broken, that control the DTR RTS signals.

but how can it be damaged with sofware problem? It was only some kind of hard fault...
