TDA4VM: TDA4 mipi csi lane speed problem

Part Number: TDA4VM

Hi,

We want to acquire two 8MP camera images. Modify the csi rate to CSIRX_LANE_BAND_SPEED_2250_TO_2500_MBPS,but no video stream and data. Is there any reason for this problem? Can csi lane speed be set CSIRX_LANE_BAND_SPEED_2250_TO_2500_MBPS?

At the same time, we did the following experiments,

     one 8MP camera, csi rate to CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, Can be displayed normally(use run_app_single_cam.sh). 

     two 8MP camera, csi rate to CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, Image is floral or abnormal,  have video stream(use run_app_single_cam.sh to select one of the cameras). 

     one 8MP camera, csi rate to CSIRX_LANE_BAND_SPEED_2250_TO_2500_MBPS, no video stream and data(use run_app_single_cam.sh).

The configuration is as follows,

static IssSensor_CreateParams ecarx_8MPCreatePrms = {
8MP_UYVY, /*sensor name*/
0x6, /*i2cInstId*/
{0, 0, 0, 0, 0, 0, 0, 0}, /*i2cAddrSensor*/
