syspara Module

This module provides the functions of obtaining and setting system attributes.

It can be used on the Hi3861, Hi3516D V300 and Hi3518E V300 platforms powered by LiteOS Cortex-M and LiteOS Cortex-A. Supported system attributes consist of default, OEM-specified, and custom system attributes. OEM-specified system attributes provide only default values. The specific values need to be adjusted as required.

How to Use

The following is an example of using syspara.

// set && get
char key1[] = "rw.sys.version";
char value1[] = "10.1.0";
int ret = SetParameter(key1, value1);
char valueGet1[128] = {0};
ret = GetParameter(key1, "version=10.1.0", valueGet1, 128);

// get sysparm
char* value1 = GetProductType();
printf("Product type =%s\n", value1);
free(value1);
char* value2 = GetManufacture();
printf("Manufacture =%s\n", value2);
free(value2);
char* value3 = GetBrand();
printf("GetBrand =%s\n", value3);
free(value3);
char* value4 = GetMarketName();
printf("MarketName =%s\n", value4);
free(value4);
char* value5 = GetProductSeries();
printf("ProductSeries =%s\n", value5);
free(value5);
char* value6 = GetProductModel();
printf("ProductModel =%s\n", value6);
free(value6);
char* value7 = GetSoftwareModel();
printf("SoftwareModel =%s\n", value7);
free(value7);
char* value8 = GetHardwareModel();
