3## 1. Failed to run the KV store on the LiteOS Cortex-A kernel \(Hi3516 or Hi3518\) due to incorrect path setting for the KV store<a name="section2041345718513"></a>
4
5**Symptom**
6
7When the LiteOS Cortex-A kernel \(Hi3516 or Hi3518 platform\) directly calls the API provided by the KV store, the compiled executable program fails to run.
8
9**Possible Causes**
10
11The compiled executable program is run directly without being converted to an application using **AbilityKit** APIs. In this case, the Bundle Manager Service \(BMS\) cannot correctly set the path for storing application data during application installation. As a result, the KV store fails to run.
12
13**Solution**
14
15Call the **UtilsSetEnv** function of the KV store to set the data storage path.
16
17```
18UtilsSetEnv("/storage/com.example.kv");
19```
