+# Linux Host Target
+
+There are a couple of limitations to this target when it comes to a test which involves system reset or test process due to Watch Dog Timer (WDT) and NVMEM implementation.
+
+- **WDT**:  Lacks functionality to recover after a hang as they just return failure or success.
+
+- **NVMEM**: Stores data in an array in memory, which means NVMEM would be lost as it isn't a non-volatile implementation.
