通过在rockchip vendor分区新增一个自定义字段，动态写入国家码，下次开机通过uboot传入系统属性
- 写入方式
- uboot 修改
写入方式
static int vendor_storage_write(int cmd, char *num)
{uint32 i;int ret ;uint8 p_buf[sizeof(struct rk_vendor_req)]; /* malloc req buffer or used extern buffer */struct rk_vendor_req *req;req = (struct rk_vendor_req *)p_buf;int sys_fd = open("/dev/vendor_storage",O_RDWR,0);if(sys_fd < 0){printf("vendor_storage open fail\n");return -1;}req->tag = VENDOR_REQ_TAG;req->id = cmd;req->len = strlen(num);printf("%s: strlen = %d\n", __func__, req->len);memcpy(req->data, num, req->len);ret = ioctl(sys_fd, VENDOR_WRITE_IO, req);if(ret){printf("vendor write error\n");return -1;}return 0;
}else if(strcmp(argv[i], "write_wifi_country") == 0)
{if (0 == vendor_storage_write(VENDOR_CUSTOM_ID_1D, argv[i+1])){printf("write_wifi_country success.\n");}printf("write_wifi_country over!\n");break;}
uboot 修改
