DCA1000EVM: Unable to connect dca1000evm

Is it because these two IDS do not match, or is there another problem

Hello ,

You mentioned that you are not able to connect to the DCA1000 from the mmwave studio. But I see that that are some data files generated with some ADC data, how were those generated if the DCA is not connecting? Which red LED light is ON on the DCA1000? There would some silk screen text near the LED suggesting the name of the signal, can you provide that? Or send a clear image of the board with the LED light on.

Regards,

Vivek

1. I just guess that the dca1000 is not connected, because the normal file size should be 2002kb, but there are 0kb and 1182kb. I am also confused about this.
2. the lights are red: (SD_FULL) (DDR_FULL)( FPGA_ERR)  (LVDS_PATH_ERR) (HDR_ERR)  (EEPROM_RD_FAIL). I consulted the user's guide and did not know why so many lights were on.

Hello Xingran,

So ALL of the RED lights get ON? At what point do they turn ON and do they remain ON or do they go OFF after some time? These lights will come on during power up of the DCA1000 board and then turn OFF when the FPGA code gets loaded to the FPGA from on board memory. Did you try reflashing the DCA1000 binary using the diamond tool ? 

Are you using mmwave studio to control and configure the DCA1000 and 1642 device?

Hello Vivek：

1. These red lights are always on after plugging in

2.I tried to rewrite with the FPGA, but during the erasure process,

there was a problem, which I mentioned in the problem statement.

As shown in the figure above, using diamond software,

the erasure was successful but the rewrite failed,

and I strictly followed section 9.2 in the manual.

Below will show all the settings I have set up with diamond software so that you can look for the problem.

The image above shows that the erase was successful.

This is the re-flashed configuration.

The flashing failed, and I can't find out the cause of this error.

3.The mmwave studio can configure the radar normally,

but an error occurred when connected to the DCA1000EVM,

showing that the FPGA version could not be searched.

Hello Xingran,

Are you providing the 5V supply to the DCA1000? Can you share an image of the just the DCA1000 (without connecting the 1642boost board) with the LED settings?

Vivek

Hello Xingran,

If you press the "FPGA PROGRAM" switch SW4 what happens?

I assume you were able to capture data using this DCA initially and now its not working, is that correct?

No change after pressing.However FPGA_PROGRAMN_LED and FPGA_INITN two lights will light up, and if you stop pressing, the two lights will go out. The few red lights that appeared wrong did not change, and the re-power supply did not work. Previously, the DCA1000 could indeed collect data normally

I think there is no FPGA in the dca1000 after I erase the FPGA and fail to write it again.

Therefore, reprogramming is probably not a solution.

So, should we solve the problem of rewriting first?

Or do you have other points of view?

Hello Xingran,

You are right, looks like you have ended up erasing the FPGA code. You need to try re-flashing the fpga. Which binary file are you trying to flash, did you find the file from the mmwave studio package?

This one

Hello Xingran,

The binary is correct. If the board is working fine you should be able to flash the FPGA binary using the Diamond programmable tool provided by Lattice.

If you are unable to do so it might indicate the board has got damaged (since you mentioned you are following the exact procedure from the user guide). You could also double check your procedure once again if you would like to.

Hello Xingran,

Did you try the flashing again? If it still did not work can you check if there is any other usb cable connected to the same PC? If yes can you remove them before attempting to reflash the FPGA binary?

Vivek
