help
When 240MHz is selected, esp_flash_write_encrypted() will automatically limit CPU frequency during
execution:
- v1.2 and above chips: limited to 160MHz
- v1.0 and below chips: limited to 80MHz
When 160MHz or lower is selected, no frequency limiting occurs during encrypted writes. Please refer to
the ESP32-C5 SoC Errata document for more details.
Due to known silicon issue, CPU frequency will be fixed to 160 MHz when flash encryption is enabled. Please
refer to the ESP32-C5 SoC Errata document for more details.
