Hello experts

my question is i have a slave device connected to my ESP32 and i need to reset this slave device at some time
the reset pin of the slave device is connected to my GPIO pin

please see attached picture

I want to put a GPIO pin in high impedance mode at boot up time ...

Thanks

I have another question in my mind since ESP32 nodemcu does not have any internal flash memory

• Does the CPU directly run the application code/instruction from external flash or does it load the application instructions part by part into the RAM and then execute from RAM

.
