How to hold a physical boot or reset buttons in ESP32-S3?

Hello, I am designing a PCB that’s using the built-in serial/JTAG controller and OTG peripheral of the ESP32-S3. It can not hold a physical boot or reset buttons. It has a USB-C container with the D/D- lines connected to GPIO20 and ...Read more

Hello,

I am designing a PCB that’s using the built-in serial/JTAG controller and OTG peripheral of the ESP32-S3. It can not hold a physical boot or reset buttons. It has a USB-C container with the D/D- lines connected to GPIO20 and GPIO19, respectively.

Are there any ways of going without buttons for reset or is an external USB to UART IC needed?

For boot mode choosing I exactly hold a jumper that when shorted pulls GPIO0 to GND, is there a better way to do that without a button?

Any help is appreciated.

Thank You

    Hello, The USB-serial-JTAG port can usually reset/put the chip into boot mode without any external components. It's still advised to have some way to pull IO0 low for initial programming and during development, if you make a mistake where e.g. your program disables the USB function. A jumper will peRead more

    Hello,

    The USB-serial-JTAG port can usually reset/put the chip into boot mode without any external components. It’s still advised to have some way to pull IO0 low for initial programming and during development, if you make a mistake where e.g. your program disables the USB function. A jumper will perform that function just fine.

    Thank You

While using ESP32-S3-WROOM-1-N8R8 module for my application. I used GPIO20 as a GPIO input for switch application. I have used external pull up for digital high or low. But in that pin ,there is an inbuilt internal pullup. But it isn’t mentioned in datasheet.

Kindly suggest how to change that pin to Hi-Z state.
