 ## What If the ESP-IDF Version Is Lower than the `Required` Version?
 
 Latest ESP-IDF versions can prevent from downloading to, or even execute binaries on unsupported chips. ESP-IDF of versions v4.4.5+, v5.0.1+, v5.1 and above have both esptool download check and bootloader loading check against the chip revision. While ESP-IDF v4.3.5 has only esptool downloading check.
