 ## 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.

-                NOLOAD section, not included in the final binary file. This reduces flash usage by
-                approximately 10% - 35%. The esp_log() function uses the binary log handler to output
-                messages. Instead of sending the full log string, the chip transmits only the
-                addresses of these strings (if present in the ELF file). If the format string
-                cannot be found in the ELF file, the chip sends the entire string. The host-side
-                monitor tool, which has access to the ELF file, reconstructs the log message using
-                the format string.
-                This reduces firmware size by eliminating format strings from
-                flash memory and removing the usage of printf-like functions, potentially freeing up
-                a few kilobytes of space. To further reduce firmware size, wrap string data with ESP_LOG_ATTR_STR.

- * - 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

- * - 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
