Set USB port & Compile or install mkspiffs

[arjfca]

Hello


Trying to install some code on a ESP32 but i'm stuck. I'm lost.
The original project is from this site. A Bluetooth thermometer interface gateway to wifi.
https://github.com/dereulenspiegel/ibbq-gateway

I did followed these procedures to install some code on an ESP32

Clone this repository somewhere
Connect the ESP32 board to your computer
Setup the ESP-IDF
Set the correct USB port via make menuconfig (see ESP-IDF documentation)
Compile or install mkspiffs
Change into the directory where you cloned this repository
Execute make flash_spiffs, wait for it to finish
Execute make flash, wait for it to finish

From these procedures,
- from a command line, How do I set a USB port to talk with the ESP32?
- How do I compile or install mkspiffs?

Any help appreciated
