1. Significance of NVRAM warning
The Wi-Fi driver detects the mt6620 Wi-Fi NVRAM status on the mobile phone. If the detection result is incorrect, the error code is displayed on the scan result.
This aims to expose some hidden problems to the prompt. For example, if Wi-Fi NVRAM is not configured, the default value/setting of Wi-Fi is incorrect, which may cause Wi-Fi driver exceptions, such as signal deterioration. In this case, Wi-Fi is available, but there may be some potential problems.
In order to learn early that the NVRAM config is incorrect and eliminate the problem of not driver or protocol, we will display the NVRAM-related error on scan result in error code number mode.
