System startup interrupted due to “parse failed!” error

Problem

During system startup, the error message “[Init] InitReadCfg, parse failed! please check file /etc/init.cfg format.” is displayed, and the startup is interrupted, as shown in the following figure.

Figure 1 Error information

Cause

During the modification of the init.cfg file, required commas (,) or parentheses are missing or unnecessary ones are added. As a result, the file’s JSON format becomes invalid.

Solution

Check the init.cfg file and ensure that its format meets the JSON specifications.

System automatically restarted again and again

Problem

After the image burning is complete, the system keeps restarting.

Cause

Each service started by the init process has the importance attribute, as described in Table 3 in Job Management.

If the attribute value is 0, the init process does not need to restart the development board when the current service process exits.
If the attribute value is 1, the init process needs to restart the development board when the current service process exits.

During the startup of a service whose importance is 1, if the service exits due to a process crash or an error, the init process automatically restarts the development board.

Solution

View logs to identify the service that encounters a process crash or exits due to an error, rectify the issue, and then burn the image again.
Alternatively, change the value of importance to 0 for the service that exits due to a process crash or an error, and then burn the image again. In this way, the development board will not be restarted even if the service exits.

Failed to call the SetParameter or GetParameter API with correct parameter values

Problem

Calling the SetParameter or GetParameter API fails even if correct values are passed to all input parameters.

Cause

Permission verification has been enabled for the SetParameter and GetParameter APIs. If the UID of the caller is greater than 1000, that is, the caller does not have the permission to call these APIs, API calls will fail even if the parameters are correct.

Solution

No action is required.
