So I am designing a dev board based on ESP32-C3 (ESP32-C3FN4) and I am not sure if I am correct with connections for download boot.
Is it enough to put tactile switched on GPIO2 and GPIO8 towards VCC and pull-down on GPIO9.
Also should I include connector in case the device needs to be flashed?

Re: ESP32-C3 putting device into download boot
U need to start your esp32 with Low level on Boot pin for begin bootloader.In normal mode u can hold HIGH level on this pin by pullup him with 10k, for example. Usually u can use 2 buttons for switching mode, 1 - for connect boot pin to GND, 2 - for pull RST(EN) pin to GND - for restarting esp32(u need to pullup it too).Also u can use special schemes which will do it automatically

Thanks, can you please provide me with special schematics for auto boot?
Also would you put programming header in case bootloader fails?
