wdr问题

现在接入sc533hai的sensor，线性模式没问题，跑wdr的时候报错如下：
[sample_comm_vi_set_grp_info]-1299: vi set wdr fusion grp attr failed!
[sample_comm_vi_start_vi]-2496: set grp info failed!
[sample_venc_vi_init]-875: sample_comm_vi_start_vi failed: 0xffffffff
[sample_venc_online_wrap_start_sys_vi_vpss]-1592: Init VI err for 0xffffffff!
program exit abnormally!

排查vi配置如下：

static td_void sample_comm_vi_get_default_grp_info(sample_sns_type sns_type, sample_vi_grp_info *grp_info)
{
td_u32 i;
td_u32 pipe_num;
ot_size size;

sample_comm_vi_get_size_by_sns_type(sns_type, &size);
grp_info->grp_num = 1;
grp_info->fusion_grp[0] = 0;

grp_info->fusion_grp_attr[0].wdr_mode = sample_comm_vi_get_wdr_mode_by_sns_type(sns_type);
grp_info->fusion_grp_attr[0].cache_line = size.height;
pipe_num = sample_comm_vi_get_pipe_num_by_sns_type(sns_type);
for (i = 0; i < pipe_num; i++) {
    grp_info->fusion_grp_attr[0].pipe_id[i] = i;
}
printf("===grp_info->fusion_grp_attr[0].wdr_mode = %d\n",grp_info->fusion_grp_attr[0].wdr_mode );

}

排查驱动代码如下：

/**

• global variables
  */
  static cis_info g_sc533hai_info[OT_ISP_MAX_PIPE_NUM] = {
  [0 …(OT_ISP_MAX_PIPE_NUM - 1)] {

   .mutex = PTHREAD_MUTEX_INITIALIZER,
   .sns_id = SC533HAI_ID,
   .fswdr_mode = OT_ISP_FSWDR_NORMAL_MODE,
   .quick_start_en = TD_FALSE,
   .fast_ae_en = TD_FALSE,
   .max_short_exp = SC533HAI_SEXP_MAX_DEFAULT,
   .bus_info = { .i2c_dev = -1 },
   .sns_state = TD_NULL,
   .blc_clamp_info = TD_TRUE,
   .mode_tbl = {
        /* mode 0: linear */
       {
           SC533HAI_VMAX_LINEAR,
           SC533HAI_FULL_LINES_MAX_LINEAR,
           SC533HAI_FPS_MAX_LINEAR,
           SC533HAI_FPS_MIN_LINEAR,
           SC533HAI_WIDTH_LINEAR,
           SC533HAI_HEIGHT_LINEAR,
           SC533HAI_MODE_LINEAR,
           OT_WDR_MODE_NONE,
           "SC533HAI_5M_30FPS_10BIT_LINEAR_MODE"
       },
       /* mode 1: WDR */
       {
           SC533HAI_VMAX_2TO1_LINE_WDR,
           SC533HAI_FULL_LINES_MAX_2TO1_LINE_WDR,
           SC533HAI_FPS_MAX_2TO1_LINE_WDR,
           SC533HAI_FPS_MIN_2TO1_LINE_WDR,
           SC533HAI_WIDTH_2TO1_LINE_WDR,
           SC533HAI_HEIGHT_2TO1_LINE_WDR,
           SC533HAI_MODE_2TO1_LINE_WDR,
           OT_WDR_MODE_2To1_LINE,
           "SC533HAI_5M_30FPS_10BIT_2TO1_VC_MODE"
       },
   },
   .i2c.fd = -1,
  

  }
  };
  请问下，是什么原因呢，怎么解决呢？
