TDA4 add 8M YUV camera can not get frame

the des and ser register IIC write success

Hi xu ji,

Can you please make sure to change the output data format to YUV422 in Deserializer? Any virtual channel id or CSI output lane speed? 

Regards,

Brijesh

yes, config to YUV422 8bit output and  virtual channel id is 0 lane speed is 1.5Gbps per lane

ok, can you please make sure to start streaming from sensor/deserializer only on streamon callback? 

yes， I think so, the flow is not changed

Any change in lane speed or CSI instance being used?

CSI instance not changed,where about set lane speed?

oh ok, can you please below try using below parameters? Btw, which SDK release are you using?

static IssSensor_CreateParams gw_8bxmaxCreatePrms = {

I am use the 0703 SDK

In SDK7.3, the single camera example uses the default speed, which is already set to 1.5Gbps. So no change required. Are you sure that the sensor/deserializer is configured correctly and is outputting YUV422 data format? Is the output also tagged as UYVY format in deserializer? 

yes,the sensor/deserializer config can be frame out in the FPGA  des test box,so I use that config on TDA4 driver but can not get frame

and how to know TDA4 CSI receive correct frame or not?

single camera example uses the default speed, which is already set to 1.5Gbps.

how to change single camera example speed higher than 1.5Gbps?

when I add this TIVX_CAPTURE_LANE_BAND_SPEED_1350_TO_1500_MBPS

it build error report undefined it

Hi xu ji,

In SDK7.3 release, we cannot directly use it. we need to include capture node's header file in the sensor in order to use this macro. 

But i thought you are using 1.5Gbps lane speed, so why do you want to change/increase lane speed? 

One possible easy quick way is to change it in the tivx_capture_params_init API, or may be, after you call this tivx_capture_params_init API in application, change tivx_capture_params_t.instCfg[loopCnt].laneBandSpeed variable in the example. 

I am still doubting in the starting of the streaming from FPGA. Could you please check and double confirm that streaming is enabled/started only in streamon callback in FPGA?
