Hello
The response is
(initramfs) /ventoy/tool/vtoydump -f /ventoy/ventoy_os_param -c sdb -v
get os param from file /ventoy_os_param
Failed to open file /ventoy_os_param error 2
ventoy os param not found 2
(initramfs)

I don't knwon why it use  /ventoy_os_param  as the file name. Obviously you input /ventoy/ventoy_os_param

Code:

int rc;
    int ch;
    int print_path = 0;
    char filename[256] = {0};
    char diskname[256] = {0};
    char device[64] = {0};
    ventoy_os_param *param = NULL;
   
    while ((ch = getopt(argc, argv, "c:f:p:v::")) != -1)
    {
        if (ch == 'f')
        {
            strncpy(filename, optarg, sizeof(filename) - 1);
        }
        else if (ch == 'v')
        {
            verbose = 1;
        }
        else if (ch == 'c')
        {
            strncpy(device, optarg, sizeof(device) - 1);
        }
        else if (ch == 'p')
        {
            print_path = 1;
            strncpy(filename, optarg, sizeof(filename) - 1);
        }
        else
        {
            fprintf(stderr, "Usage: %s -f datafile [ -v ] \n", argv[0]);
            return 1;
        }
    }

    if (filename[0] == 0)
    {
        fprintf(stderr, "Usage: %s -f datafile [ -v ] \n", argv[0]);
        return 1;
    }

    param = malloc(sizeof(ventoy_os_param));
    if (NULL == param)
    {
        fprintf(stderr, "failed to alloc memory with size %d error %d\n",
                (int)sizeof(ventoy_os_param), errno);
        return 1;
    }
   
    memset(param, 0, sizeof(ventoy_os_param));

    debug("get os pararm from file %s\n", filename);
    rc = vtoy_os_param_from_file(filename, param);
    if (rc)
    {
        debug("ventoy os param not found %d\n", rc);
        goto end;
    }
