help
Flash suspend has defect on ESP32C6 until v0.2 and ESP32H2 until v1.2. If you already use suspend
feature for massive protection, you can enable this for bypassing check after knowing the risk.
But if you are new users, or developing new applications, or producing a new batch,
please DO NOT enable this config option.
For more information, please refer to errata or connect to Espressif business support team.
