 ## 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.

- * - This strategy is viable because the bootloader runs exclusively

- *
- * ESP-TEE (Trusted Execution Environment)
- * - Cannot adopt the strategy used by the bootloader as the TEE app operates
- *   in parallel to the REE.
- * - The few initial MMU entries have already been taken by the TEE and REE
- *   application flash IDROM segments.
- * - The REE could have also mapped some custom flash partitions it requires.
- * - Therefore, the TEE uses MMU entries from the end of the range, with the number
- *   of entries corresponding to the size of its IDROM segment sizes.
- * - The final MMU entry in this range is reserved for flash reads through the
- *   cache (auto-decryption).
- * - The pages used by TEE are protected by PMP (Physical Memory Protection).
- *   While REE attempts to mmap this protected area would trigger a load access
- *   fault, this is unlikely since the MMU can address up to 16MB at once.
