DCA1000EVM: DCA1000 + IWR6843ISK + mmWave Studio 02.01.01.00 Unable to perform continuous data acquisition. In addition, the connection between DCA1000 and FPGA is unstable

Part Number: DCA1000EVM
Other Parts Discussed in Thread: IWR6843

After all configurations are completed, the DCA1000 Setup sometimes fails to connect (FPGA version: 2.9). A successful connection may be achieved after a reboot.
 
After a successful connection, the error Timeout Error! System disconnected may occur during data acquisition.
 
If only the file path is changed after a successful acquisition, the error Timeout Error! System disconnected will most likely appear during the next acquisition.
 
During debugging, I tried replacing the PC, Ethernet cable, power cable, etc., but the issue remained unresolved.
 
I also attempted to downgrade mmWave Studio by one version, but this did not help.
 
Flashing the FPGA firmware to version 2.8 still failed (furthermore, I cannot find the version 2.9 firmware, so I cannot revert back to it).
 
Finally, I borrowed an identical hardware platform and tested it on the same computer.
 
With exactly the same hardware and software setup, the problem only occurs when using our DCA1000, while the other DCA1000 runs smoothly.
 
We have been trying to fix this issue for about eight months, and it still has not been effectively resolved even after referring to various tutorials.

    Hello,

    Please check the following link

    This does not match my situation. I have already tried all the solutions from various tutorials and blogs, both for software and hardware.
    As I mentioned, no errors occur when using another set of equipment under the same configuration.
    During cross‑validation between the IWR6843 and DCA1000, this problem only appears with my own DCA1000, while our radar works without any errors when paired with the other DCA1000.
    This issue has existed since I purchased the device. Could it be a hardware problem with the DCA1000?
    More importantly, this issue occurs randomly.Our workflow requires 30 one-minute data acquisitions. Sometimes the data can be captured continuously without problems, but at other times we cannot establish a stable connection for one or two days.This is the most frustrating part for us.

    If this only occurs on one DCA1000, then there is probably something wrong with it. Especially if nothing changes after reflashing the FPGA. These EVMs are very sensitive to ESD and its possible a small part is malfunctioning.

    Indeed, I did reflash the FPGA firmware during my previous troubleshooting attempts. Following the tutorial, I located the firmware file in the corresponding directory, but it turned out to be version 2.8. The original firmware version when I purchased the device was 2.9, and I confirmed the successful flashing because the version number changed upon connection afterward. Unfortunately, this did not improve the smoothness of my subsequent data acquisition operations.
    Now I wish to revert back to version 2.9, but I cannot find the version 2.9 firmware in the directory. I would like to know how to locate this specific firmware version. Additionally, since this issue has existed since the date of purchase, am I eligible to apply for after-sales service?

    Hello,

    You can contact TI customer service and discuss replacement details with them.

    I tried collecting data again. The first connection to the FPGA was unsuccessful, but the second attempt succeeded, and I completed three data acquisitions. I will now post the logs below:

    This is what it looks like after the failure.

    It is worth noting that after the time out prompt appeared, the acquisition indicator light still kept flashing intermittently until the set acquisition event finished.

    However, no data was collected in this failed attempt, unlike the previous three successful ones.

    The chirp profile seems okay, based on the values used for configuration. Have you tried a default configuration of some sort? The timeout error is from the Radar sensor itself not starting. The FPGA error is communication exclusively between PC and DCA1000 but that seems to have been sorted out. Can you take a picture of your physical setup? Have you ever been able to capture data successfully?

    I have successfully achieved signal acquisition under this configuration. The issues are consistent with those mentioned in our previous conversation: there is a probability (approximately 50%) of failing to connect to the FPGA, and a 30% probability of establishing a successful connection. After acquiring the signal for 60 seconds, I change the folder path, and then a time-out error pops up (this is exactly what happened this time: the connection was disconnected after three sets of acquisitions). Only a small percentage of attempts allow for multiple consecutive acquisitions.
    I have tried replacing the cable, PC, adapter, or using a direct connection, but the problem remains unsolved. You can refer back to our earlier discussion—this appears to be a malfunction of the DCA1000, as I tested with another set of equipment purchased at a different time, and the problem only occurs when using my DCA1000 alone.
    In addition, I have another question: I would like to know how to find the latest version of the FPGA firmware. When I checked, I found that only version 2.8 of the firmware is available in the directory specified in the manual, but the latest version should be 2.9.

    You can get steps to reflashing the FPGA starting from page 22 of the DCA1000 PDF User Guide.

    https://www.ti.com/lit/ug/spruij4a/spruij4a.pdf

    For your convenience I have attached 2.9 below

    Thank you for your reply. However, when I clicked on the URL, it prompted "You do not have permission to view this directory or page." What could be the reason for this?
    If possible, could you please send the file to my email address: 18541244522@163.com? Thank you very much again.
