 ## 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.

+File    : SEGGER_SYSVIEW_Conf.h
+Purpose : SEGGER SystemView configuration file.
+          Set defines which deviate from the defaults (see SEGGER_SYSVIEW_ConfDefaults.h) here.
+Revision: $Rev: 21292 $
+
+Additional information:
+  Required defines which must be set are:
+    SEGGER_SYSVIEW_GET_TIMESTAMP
+    SEGGER_SYSVIEW_GET_INTERRUPT_ID
+  For known compilers and cores, these might be set to good defaults
+  in SEGGER_SYSVIEW_ConfDefaults.h.
+
+  SystemView needs a (nestable) locking mechanism.
+  If not defined, the RTT locking mechanism is used,
+  which then needs to be properly configured.
