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.
