AWR2944: receive data from CSI2

Hi ,

I found a similar case(RTOS/TDA2P-ACD: CSI2 PHY RESET_DONE is not coming - Processors forum - Processors - TI E2E support forums)

but i don't know how did they solve it.

How to enabling de-serializer.

Hello Marvin,

Could you ask the customer to share the sysconfig generated files?
From there we can figure out how what is causing the issue on the reset_phy.

Hello Saswat ,

This case has any solution？

Looking forward to your reply。

thanks!

Hello guilin shi,

These are not the sysconfig generated files. This is just the config file.
Could you share me the file named ti_drivers_open_close.c ?

Regards,
Saswat Kumar

Hello Saswat,

This is the file message for di_drivers_open_close.c

============

============

The result of my inspection is int the functin "CSIRX_complexioIsResetDone"   the  isResetDone set false.

Description of Technical Manual the CSI2_CONPLEXIO_CFG[29] RESET_CTRL be set to 0x1 when CSI2_CONPLEXIO_CFG[30] RESET_CTRL set 0x1.

When I run the program,the  CSI2_CONPLEXIO_CFG[29] RESET_CTRL always 0x0  when CSI2_CONPLEXIO_CFG[30] RESET_CTRL set 0x1.

Hello Saswat,

Because our working hours are inconsistent，Can you tell me how to correctly configure the CSI2 module and inspection methods.

Since this is the first time for me to configure the CSI2 module, I don't know if my configuration method is wrong.

thanks!

Hello Saswat,

I change this step,it can break from this loop when i transmitter.

but the interrupt callback function(App_csirxCommonCallback) not triggered。

When i  send debug frame used function(CSIRX_debugModeGenerateFrames),the  interrupt callback function(App_csirxCommonCallback)  can triggered.

Regards,

guilin.shi

Hello Guillin Shi,

Could you please explain when you are facing issue?
What are you using as the Tx, what is the callback used for? and in which case are you not able to see it?

Regards,
Saswat Kumar

Hello Saswat,

I want receive data from FPGA by csi2 mode.

I running csirx example, the interrupt callback function(App_csirxCommonCallback)  can triggered when i send data by CSIRX_debugModeGenerateFrames function.

I want the callback function can trigger when csi2 mode receive data.

In this function ,i just record trigger count for let me know I got the data.

Regards,

guilin.shi

Hello shi guillin,

Could you confirm whether the data you are receiving from the FPGA is getting populated in the AWR2944? Please do also let me know how you are confirming this step.

Regards,
Saswat Kumar

Hello Saswat,

I can see the sent data through the FPGA debugger，and csi2 data lan clock lan will change.

but I don't know whether the data is actually received and whether the data format matches correctly。

Is there any way to confirm whether AWR2944 have received valid data？

Regards,

guilin.shi

Hello Shi Guillin,

So, if you have written your custom application, you could select the ping/pong address for the CSI2 lines data to be received in the L3 for cross verification.
If you are able to see our data there, that means the data is actually being streamed in the proper format.

Regards,
Saswat Kumar

Hello Saswat,

I use the following code to set buff and context.

========

========

The buff has data when when i send data by CSIRX_debugModeGenerateFrames function.

But buff has't data when when i send data by FPGA.

From FPGA  TX to AWR2944 RX, I don't know which module is the problem。

Hello Shi Guilin

shi guilin said:

.pingPongConfig =

        {

            .pingAddress = 0,

            .pongAddress = 0,

            .lineOffset = 0,

            .pingPongSwitchMode = CSIRX_PING_PONG_LINE_SWITCHING,

            .numFramesForFrameBasedPingPongSwitching = 1,

            .numLinesForLineBasedPingPongSwitching = 2,

        },

Here you have set the pingpong config to address as 0. could you please modify this and then run, rebuild and let me know.

Hello Saswat,

This problem has been solved，because the data format sent by FPGA is wrong(Frame start and Frame end not sent as expected).

we can closed this case,Thank you for your support！！！

guilin.shi

Hello Saswat,

I have another question,  can i change pingpong address when the program is running.
