+                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.
